O uso da técnica de assimilação de dados meteorológicos é extremamente importante para a correção de imprecisões nos dados que compõem as condições iniciais e de fronteira dos modelos de previsão do tempo. Neste trabalho, faz-se uso da técnica de assimilação de dados 3DVAR contida no modelo de mesoescala WRF (Weather Research and Forecasting), o objetivo principal do trabalho é analisar o impacto da assimilação de dados meteorológicos de diversas fontes de dados (GTS – Sistema Global de Telecomunicações, estações automáticas, dados radar) no modelo WRF. Para analisar a consistência da assimilação de dados no WRF verificou-se a diferença entre a análise com e sem assimilação de dados. Confirmando a consistência da mesma, foram realizados os procedimentos necessários para gerar os prognósticos com assimilação de dados para cada caso individualmente. Os experimentos com assimilação de dados foram realizados para cada tipo de dado e em conjunto, possibilitando assim fazer uma análise do impacto que cada dado tem na previsão. Os resultados foram comparados entre si espacialmente utilizando dados do modelo global GFS (Global Forecast System) e satélite da Missão de Medida da Chuva Tropical (TRMM). A variável da precipitação acumulada foi comparada e validada espacialmente com os dados do TRMM, constatou-se para o caso do mês de janeiro uma superestimação dos valores acumulados para algumas regiões e para o caso do mês de abril uma subestimação, isso se deve ao fato da frequência temporal dos dados do satélite TRMM, pois provavelmente elas não foram compatíveis com o horário das precipitações. Quando comparado com o volume de chuva pontual com os dados da estação automática a maioria dos processamentos mostrou-se eficaz. Também no estudo de caso ocorrido no mês de janeiro a inserção de dados assimilados possibilitou uma melhora na intensidade e localização da célula convectiva. As variáveis da temperatura e do vento foram comparadas espacialmente com as análises do modelo GFS. A variável da temperatura ora apresentou valores superiores, ora inferiores ao modelo GFS, mesmo assim os resultados foram satisfatórios, uma vez que, foi possível simular temperaturas superiores antes da passagem do sistema e inferiores após a passagem do mesmo. Para o campo de vento houve uma pequena discrepância em todas as simulações em relação a magnitude, porém a direção do vento foi plotada de forma coerente, simulando até o ciclone presente no caso do mês de abril. Para o perfil vertical da temperatura e temperatura do ponto de orvalho o impacto da assimilação de dados foi pequeno, porém ambas as simulações representaram de forma coesa os perfis quando comparados com o perfil observado. Em suma, o estudo comprova que, embora se tenha algumas incoerências assimilação 3DVAR contribui de modo significativo nas previsões do tempo do modelo WRF.

The use of meteorological data assimilation technique is extremely important for the correction of the imprecisions of observational data for the initial and boundary conditions of weather forecasting…

Este trabalho investiga o comportamento espaço-temporal da precipitação pluvial na Região Sul do Brasil entre 1988 e 2007. A avaliação concentrou-se em três aspectos: 1) principais características climatológicas, 2) tendência geográfica, com base nas feições do relevo, e 3) principais modos de variabilidade. Foram utilizados dois conjuntos complementares de dados de precipitação: postos pluviométricos e estimativas de precipitação do satélite Tropical Rainfall Measuring Mission (TRMM), produto 3B43. A avaliação das feições do relevo foi conduzida com o auxílio do Modelo Digital de Elevação (MDE) oriundo do Shuttle Radar Topography Mission (SRTM), a partir do qual foram identificadas três sub-regiões: 1) Litoral, 2) Campanha e 3) Planalto. As características climatológicas da precipitação foram avaliadas através de estatísticas descritivas (média e desvio padrão) sazonal e anual. A análise de tendência geográfica foi realizada para cada sub-região identificada através de regressão linear múltipla da precipitação em relação às suas coordenadas (latitude e longitude). A variabilidade da precipitação foi avaliada por meio de Funções Ortogonais Empíricas (EOF), enquanto os sistemas atmosféricos responsáveis pelos principais modos de EOF foram investigados a partir dos boletins Climanálise. Os resultados da climatologia, quando comparados a estudos anteriores, apontam uma diminuição da participação da precipitação de inverno na região, e um aumento nas estações de transição, especialmente na primavera. Os desvios em relação à média variaram entre 40% e 70%. A tendência geográfica da precipitação foi mais expressiva na metade quente do ano no Litoral, em função da Zona de Convergência do Atlântico Sul (ZCAS) e de precipitações orográficas. Nos meses frios, a tendência foi mais pronunciada na Campanha devido aos sistemas frontais e ciclones extratropicais. No Planalto, a tendência mostrou-se moderada no verão devido a ZCAS; e no outono, por conta da atuação dos sistemas frontais e ciclones extratropicais. Os principais modos de variabilidade da precipitação têm como causas distintos sistemas. No inverno, destaca-se a atuação de sistemas frontais semi-estacionários, favorecidos por episódios de bloqueios atmosféricos. No inverno e estações de transição, destaca-se a atuação dos ciclones extratropicais, em geral em associação com sistemas frontais. Nos meses quentes, os Complexos Convectivos de Mesoescala são os principais responsáveis pela variabilidade observada.

This work investigates the space-temporal behavior of rainfall in Southern Brazil during the 1988 and 2007 period. The evaluation was based on three features: 1) climatological aspects, 2) geographic trends from relief features, and 3) main variability modes. Two complementary data sets of rainfall were used: rain gauges and rainfall estimates from the Tropical Rainfall Measuring Mission (TRMM), product 3B43. The assessment of relief features was made using the Digital Elevation Model (MDE) from Shuttle Radar Topography Mission (SRTM), where three sub regions…

▼ A região amazônica desempenha papel fundamental na regulação do clima, tanto em escala regional quanto em escala global. A precipitação na região é bastante heterogênea, sobretudo devido à vasta extensão territorial da Amazônia. Dentre os sistemas responsáveis pela precipitação, alguns se destacam como eventos extremos de tempestades, como pode ser verificado em diversos estudos anteriores. Contudo, diferentemente das latitudes médias, na região tropical não há um conjunto de definições amplamente conhecido e difundido para identificação de tempo severo. O presente estudo busca identificar um critério para identificação de tempo severo na região amazônica a partir da base de dados Precipitation Features (PF) 1998 a 2012 - gerados e armazenados pela Universidade de Utah, com base nos dados do satélite TRMM. Além disso, identificar características sinóticas associadas ao ambiente de ocorrência destes eventos, através de composições com dados da reanálise CFSR-NCEP, bem como parâmetros importantes na identificação de tempestades. Utilizando o subconjunto PCTF do Nível 2 da base de dados PF, o critério estabelecido para identificação de casos severos compreende sistemas com: 80 pixels ou mais PCT85 GHz <250 K; 1 pixel ou mais com PCT85 GHz < 100 K; volume de chuva convectiva maior do que 1000 mm/h km2 e pelo menos um registro de raio. Comparando os sistemas selecionados pelo critério com os Sistemas Convectivos de Mesoescala já catalogados é possível notar que a distribuição sazonal é semelhante, embora as estações com maior número de casos sejam as estações de transição (primavera e outono, 429 e 223 casos respectivamente). Analisando as altas taxas de raios destes sistemas, fica evidente que o critério realmente seleciona casos severos. Com a região amazônica dividida em seis sub-regiões e os casos acumulados por trimestre (JFM, AMJ, JAS, OND) sub-região Southern Amazonia (SA) contabiliza o maior número de casos, com um total de 271 para o período do estudo, sendo OND o trimestre com maior ocorrência (135), o menor AMJ (29). O mês de outubro chama atenção para esta sub-região como o mês com maior número de casos, totalizando 59, dos quais 83% ocorrem a partir das 12 horas local. Estes casos foram investigados nas composições de reanálise, assim como os casos a partir de 12 horas local de outubro da sub-região Central Amazonia (CA). De forma geral: 1) SA tem maior área com cisalhamento médio mais intenso (8 m/s) do que CA, principalmente para 00Z, 06Z e 12Z; 2) valores médios de divergência positiva do vento em 200 hPa mostram-se mais significativos para CA do que para SA; 3) convergência do vento em 950 hPa é mais evidente para SA do que para CA e 4) CA é predominantemente mais úmida em baixos níveis do que SA. Histogramas com valores pontuais para cada um destes casos, em ambas as sub-regiões, são apresentados no intuito de auxiliar a identificação destes casos por previsores. O critério de identificação de tempo severo na Amazônia mostra-se eficiente, sendo o cisalhamento do vento entre 500-850 hPa e a convergência… Advisors/Committee Members: Dias, Maria Assuncao Faus da Silva.

▼ A precipitação é considerada um elemento fundamental e de grande importância no ciclo hidrológico, pois é através dela que é feita a recarga hídrica nas bacias hidrográficas e nas reservas subterrâneas.O monitoramento meteorológico é de grande importância para as nações, este monitoramento pode ser feito através de diversos métodos e instrumentos, sejam eles terrestres ou orbitais. No Brasil problemas relacionados à seca tornam-se preocupantes e estão presentes na sociedade moderna. O estudo e entendimento de comportamentos de padrões espaciais de informações sobre precipitações é uma ferramenta importante para a tomada de decisão. Observações obtidas por sensores a bordo de satélites artificiais na órbita da Terra auxiliam na medição do volume de chuva em uma dada região. Para esta dissertação foram utilizados como materiais um conjunto de dados gratuitos de precipitação do TRMM (TROPICAL RAINFALL MEASURING MISSION) através de um dos seus produtos disponíveis chamado de Rainfall Product (3B43). Atualmente estes recursos vêm sendo utilizado em diversas pesquisas onde entre suas vantagens encontram-se: a periodicidade de amostragem (resolução temporal) e abrangência superior às estações meteorológicas. Porém, as observações dos sensores orbitais apresentam algumas desvantagens como, por exemplo, a resolução espacial da informação da precipitação, sendo recomendado estabelecer critérios para as análises e validação das estimativas. Sendo assim, além de dados orbitais, informações sobre séries históricas de precipitação obtidas por estações meteorológicas que são operados por diversos órgãos públicos foram utilizadas. Desta forma, foram delineados objetivos para essa pesquisa sendo eles: (i) avaliar os dados do TRMM, a fim de valida-los como um instrumento de monitoramento de precipitação para o Brasil; (ii) comparar as informações históricas do TRMM as respectivas estações de campo em amostras no território brasileiro e assim determinar a correlação entre estes produtos; (iii) Avaliar os dados TRMM de precipitação com base no período de 2000 até 2014 aplicando um teste de normalidade a fim de verificar regiões onde existe maior igualdade estatística entre os produtos. Para a avaliação e validação dos dados do produto TRMM 3B43 em relação às séries históricas das estações meteorológicas, foram feitas análises estatísticas como a correlação entre os dados e o teste de Kolmogorov-Smirnov entre as duas Grades de informações. Espera-se através desta pesquisa contribuir com o uso e divulgação de informações temporais do TRMM para o monitoramento de precipitação no território brasileiro. Através da análise estatística entre os dois conjuntos de dados, percebeu-se que há sim a possibilidade de utilização dos dados do satélite TRMM para verificar o comportamento das curvas de precipitação, contribuindo ainda mais em regiões onde há escassez de dados in situ como o caso da região Amazônica.

▼ Error characteristics associated with satellite-derived precipitation products are important for atmospheric and hydrological model data assimilation, forecasting, and climate diagnostic applications. This information also aids in the refinement of physical assumptions within algorithms by identifying geographical regions and seasons where existing algorithm physics may be incorrect or incomplete. Examination of relative errors between independent estimates derived from satellite microwave data is particularly important over regions with limited surface-based equipments for measuring rain rate such as the global oceans and tropical continents. In this context, analysis of microwave based satellite datasets from the Tropical Rainfall Measuring Mission (TRMM) enables to not only provide information regarding the inherent uncertainty within the current TRMM products, but also serves as an opportunity to prototype error characterization methodologies for the TRMM follow-on program, the Global Precipitation Measurement (GPM) . Most of the TRMM uncertainty evaluation studies focus on the accuracy of rainfall accumulated over time (e.g., season/year). Evaluation of instantaneous rainfall intensities from TRMM orbital data products is relatively rare. These instantaneous products are known to potentially cause large uncertainties during real time flood forecasting studies at the watershed scale. This is more so over land regions, where the highly varying land surface emissivity offers a myriad of complications, hindering accurate rainfall estimation. The error components of orbital data products also tend to interact nonlinearly with hydrologic modeling uncertainty. Keeping these in mind, the present thesis fosters the development of uncertainty analysis using instantaneous satellite orbital data products (latest version 7 of 1B11, 2A25, 2A23, 2B31, 2A12) derived from the passive and active microwave sensors onboard TRMM satellite, namely TRMM Microwave Imager (TMI) and precipitation radar (PR). The study utilizes 11 years of orbital data from 2002 to 2012 over the Indian subcontinent and examines the influence of various error sources on the convective and stratiform precipitation types. Two approaches are taken up to examine uncertainty. While the first approach analyses independent contribution of error from these orbital data products, the second approach examines their combined effect. Based on the first approach, analysis conducted over the land regions of Mahanadi basin, India investigates three sources of uncertainty in detail. These include 1) errors due to improper delineation of rainfall signature within microwave footprint (rain/no rain classification), 2) uncertainty offered by the transfer function linking rainfall with TMI low frequency channels and 3) sampling errors owing to the narrow swath and infrequent visits of TRMM sensors. The second approach is hinged on evaluating the performance of rainfall estimates from each of these orbital data products by accumulating them within a spatial domain and using… Advisors/Committee Members: Kumar, D Nagesh (advisor).

This work presents the results of a impact study of estimated precipitation data assimilation in RPSAS from CPTEC, during January 2003. In this study, the precipitation assimilation was performed during the generation of first guess by the regional Eta model using a methodology similar to nudging. From this first guess, the RPSAS system generates an analysis with 20 km horizontal resolution in an area that covers South America, from which were produced 24 hours forecasts using the Eta model. Global reanalysis data from NCEP /DOE and regional reanalysis data from CPTEC were used for comparison with the tests generated with and without the precipitation assimilation. Data collected during the SALLJEX campaign, TRMM and GPCP were used for comparison with the predictions of the Eta model. The evaluation of the results was made based on statistical indices and showed that the performance of forecasts up to 24 hours of the Eta model, especially in the early hours, is significantly enhanced by the inclusion of precipitation. The values of Bias and Mean-Square Error compared with the same model without the assimilation of precipitation were minor. Also was carried out a case study of Mesoscale Convective Complex occurred during the SALLJEX campaign. The inclusion of the precipitation assimilation in the Eta+RPSAS forecasts/analysis cycle allowed to simulate a case of MCC occurred on 23 January 2003 with more details. Was also compared the wind profiles from the RPSAS analysis with the NCEP reanalysis for the occurrence of the MCC and were found a greater concordance between the profiles in relation to the profiles produced without the precipitation assimilation. Moisture flux was also calculated and showed similar values to the values produced by the NCEP reanalysis. The results of these simulations also show that besides the Eta model with precipitation assimilation, is able to play in more detail some key features of the MCC, as the spatial distribution of observed precipitation. Also the rainfall levels produced by the forecast model have been improved. This experiment also found that the use of the assimilation of TRMM precipitation in the generation of first guess improved the regional analysis produced by the CPTEC s RPSAS assimilation system and therefore increased the 24 hours forecasts produced by the Eta model. From the results, and making a few adjustments to the proposed assimilation scheme, we can study the possibility to implement operationally the assimilation of TRMM precipitation in the CPTEC s Eta+ RPSAS system in order to contribute to increasing the realism of the regional forecasts of the center, especially the short-term as well as increase the system with the use of one more source of precipitation observations.

Dans la zone intertropicale, les précipitations sont le principal marqueur climatique saisonnier et déterminent très largement l’hydrologie de surface et de nombreuses activités anthropiques. Le bassin amazonien est caractérisé par divers régimes régionaux de précipitations, dont la variabilité spatiale et temporelle est forte. De nombreux travaux ont montré que cette variabilité est liée à des forçages externes de large échelle, comme les températures de surface de l’océan. L’étude des précipitations dans cette région porte le plus souvent sur les tendances ou les extrêmes pluviométriques. En revanche, la détection d’années similaires constituant des sous-régimes régionaux et leur lien avec une configuration océano-atmosphérique particulière a été, jusqu’à présent, peu abordée. L’objectif principal de cette thèse est ainsi de créer une typologie des sous-régimes de précipitations régionaux dans le bassin amazonien et de les mettre en relation avec le contexte océano-atmosphérique pouvant en partie les expliquer. Dans ce but, des données issues de 205 pluviomètres répartis sur 5 pays du Bassin Amazonien ont été sélectionnées et soumises à une série de tests statistiques et de reconstruction. Cette thèse utilise également des données de nébulosité (Outgoing Longwave Radiation), de flux d’humidité et de température de surface de l’océan ainsi que des données satellitaires (TRMM3B42 version 7) qui permettent de compléter les informations sur la variabilité spatiale des pluies.Au sein de chacune des sept régions amazoniennes déterminées dans ce travail, deux à quatre sous-régimes de précipitations ont été détectés. Parmi les vingt-six sous-régimes, vingt sont associés à des anomalies de circulation des flux d’humidité et de température de surface des océans. Les sous-régimes de pluies de la moitié nord et les Andes de l’ouest du bassin sont le plus liés à des anomalies océaniques. De plus, comme cela est régulièrement décrit, des déficits ou excédents correspondent souvent à des phases El Niño ou La Niña, mais cette thèse met également en évidence le rôle important de l’Atlantique, en particulier sud, sur le déplacement de la ZCIT et sur les flux d’humidité ; et elle souligne également le lien entre la temporalité des événements océaniques et celle des anomalies de pluies.Le produit TRMM 3B42 V7 permet d’aller plus loin dans l’analyse de la variabilité spatiale intra-régionale des pluies de la région Nord-est du bassin amazonien et de relativiser la cohérence spatiale des sous-régimes de précipitations de cette région.

Precipitations are the main seasonal climate marker between the tropics and largely determine surface hydrolosy as well as many anthropogenic activities. The Amazon Basin is characterized by various regional rainfall patterns, whose spatial and temporal variability is high. Numerous studies have shown that this variability is related to large scale external forcing, such as sea surface temperatures. The analysis of precipitation in this region is generally related to trends or extreme of rainfall.…

▼ Access to electricity remains an impediment to development in many parts of the world, particularly in rural areas with low population densities and prohibitive grid extension costs. In that context, community-scale run-of-river hydropower – micro-hydropower – is an attrac- tive local power generation option, particularly in mountainous regions, where appropriate slope and runoff conditions occur. Despite their promise, micro hydropower programs have generally failed to have a significant impact on rural electrification in developing nations. In Nepal, despite very favorable conditions and approximately 50 years of experience, the tech- nology supplies only 4% of the 10 million households that do not have access to the central electricity grid. These poor results point towards a major information gap between techni- cal experts, who may lack the incentives or local knowledge needed to design appropriate systems for rural villages, and local users, who have excellent knowledge of the community but lack technical expertise to design and manage infrastructure. Both groups suffer from a limited basis for evidence-based decision making due to sparse environmental data available to support the technical components of infrastructure design.This dissertation draws on recent advances in remote sensing data, stochastic modeling techniques and open source platforms to bridge that information gap. Streamflow is a key environmental driver of hydropower production that is particularly challenging to model due to its stochastic nature and the complexity of the underlying natural processes. The first part of the dissertation addresses the general challenge of Predicting streamflow in Ungauged Basins (PUB). It first develops an algorithm to optimize the use of rain gauge observations to improve the accuracy of remote sensing precipitation measures. It then derives and validates a process-based model to estimate streamflow distribution in seasonally dry climates using the stochastic nature of rainfall, and proposes a novel geostatistical method to regionalize its parameters across the stream network. Although motivated by the needs of micro hydropower design in Nepal, these techniques represent contributions to the broader international challenge of PUB and can be applied worldwide. The economic drivers of rural electrification are then considered by presenting an econometric technique to estimate the cost function and demand curve of micro hydropower in Nepal. The empirical strategy uses topography-based instrumental variables to identify price elasticities.All developed methods are assembled in a computer tool, along with a search algorithm that uses a digital elevation model to optimize the placement of micro hydropower infrastruc- ture. The tool – Micro Hydro [em]Power – is an open source application that can be accessed and operated on a web-browser (http://mfmul.shinyapps.io/mhpower). Its purpose is to assist local communities in the design and evaluation of micro hydropower alternatives in their locality, while using cost and…

▼ It has been recognized that reliable, long-term and well distributed climate information is essential to inform any development policy that aims to address the consequences of climate variability and change on water resources. However, in developing countries planning of such activity is greatly hampered by the lack of a sufficiently dense network of weather stations measuring precipitation. The objective of this dissertation is, therefore, to evaluate the freely available high resolution satellite rainfall estimates in the Lake Tana Basin which has a relatively denser ground rainfall stations network. Rainfall estimates of Tropical Rainfall Measuring Mission (TRMM) 3B42 version 7, EUMETSAT's Meteorological Product Extraction Facility (MPEF), Multi-Sensor Precipitation Estimate-Geostationary (MPEG) and Climate Forecast System Reanalysis (CFSR) are considered. The satellite rainfall is validated by a direct comparison with the gauged rainfall data, and through hydrological modelling to capture the observed flow using a semi-distributed hydrological model Hydrologiska Byråns Vattenbalansavdelning (HBV) and Parameter Efficient Distributed (PED). The result of direct comparison indicated that, the MPEG and CFSR rainfall provided the most accurate rainfall estimates. On average, for 38 stations, 78 and 86 % of the observed rainfall variation is explained by MPEG and CFSR data, respectively, while TRMM explained only 17% of the variation. The hydrological modelling indicated that both the gauged and the CFSR precipitation estimates were able to reproduce the stream flow well for either of the models. The TRMM data was not be able to capture the observed flow through model calibration for both models. Bias corrected MPEG rainfall by the gauged monthly means performed as well as or better than the gauged rainfall data in capturing the observed flow through hydrologic model calibration. This dissertation has also identified potential irrigable areas by considering hydrological and landscape factors that determine lack of irrigation development in the Ethiopian highland. Potential land areas suitable for surface irrigation were determined by using a GIS based MultiCriteria Evaluation (MCE) technique by considering climate characteristics (rainfall and evaporation), land features (soil type, land use and slope), market access (town and road proximity) and proximity to a perennial river. The available water for surface irrigation was quantified by analysing historical river flow data during the dry season of the major rivers in the Lake Tana Basin. The result indicated that the main limitation for surface irrigation in the Ethiopian highlands is the availability of water and not land suitable for irrigation.

▼ The relationship between precipitation and large-flow is important to understand and characterize in the climate system. We examine statistical relationships between the Tropical Rainfall Measurement Mission (TRMM) 3B42 gridded precipitation and large-scale ow variables in the Tropics for 2000{2007. These variables include NCEP/NCAR Re-analysis sea surface temperatures (SSTs), vertical temperature pro files, omega, and moist static energy, as well as Atmospheric Infrared Sounder (AIRS) vertical temperatures and QuikSCAT surface divergence. We perform correlation analysis, empirical orthogonal function analysis, and logistic regression analysis on monthly, pentad, daily and near-instantaneous time scales. Logistic regression analysis is able to incorporate the non-linear nature of precipitation in the relation- ship. Flow variables are interpolated to the 0.25 degrees TRMM 3B42 grid and examined separately for each month to o set the effects of the seasonal cycle. January correlations of NCEP/NCAR Re-analysis SSTs and TRMM 3B42 precipitation have a coherent area of positive correlations in the Western and Central Tropical Pacific on all time scales. These areas correspond with the South Pacific Convergence Zone (SPCZ) and the Inter Tropical Convergence Zone (ITCZ). 500mb omega is negatively correlated with TRMM 3B42 precipitation across the Tropics on all time scales. QuikSCAT divergence correlations with precipitation have a band of weak and noisy correlations along the ITCZ on monthly time scales in January. Moist static energy, calculated from NCEP/NCAR Re-analysis has a large area of negative correlations with precipitation in the Central Tropical Pacific on all four time scales. The first few Empirical Orthogonal Functions (EOFs) of vertical temperature profiles in the Tropical Pacific have similar structure on monthly, pentad, and daily timescales. Logistic regression fit coefficients are large for SST and precipitation in four regions located across the Tropical Pacific. These areas show clear thresholded behavior. Logistic regression results for other variables and precipitation are less clear. The results from SST and precipitation logistic regression analysis indicate the potential usefulness of logistic regression as a non-linear statistic relating precipitation and certain ow variables.

▼ Vertical profiles of heating (Q1) are a result of the interaction between radiative heating, eddy sensible heat transport, and latent heating from cloud and precipitation systems. The third component is the largest by an order of magnitude in deep convective regions like the intertropical convergence zone (ITCZ). Vertical motion (ω) is often used as a proxy for Q1 and, in regions lacking in situ observations, ω profiles from model reanalyses are commonly used to make inferences about large-scale circulations and climate sensitivity. In the East Pacific (EP) ITCZ, ω profiles exhibit large variability between reanalyses and have a bottom-heavy shape centered near 800 hPa that contrasts with the 400 hPa peak in the West Pacific (WP) warm pool. Rainfall between the two regions is similar; however, stratiform rain fractions are higher in the EP than the WP, and the low-level ω peak in the profiles persists even during El Niño, when precipitation systems become similar between the two regions. These facts all point towards erroneous reanalysis profiles in the EP. Echo statistics from the Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar (PR) and the Dual-frequency Precipitation Radar (DPR) aboard the Global Precipitation Measurement (GPM) satellite are examined across the tropical Pacific. The DPR Ku-band is more sensitive to upper level, low-reflectivity cloud and sees more near-surface echo than the PR, but the overall echo statistics are generally similar. The addition of the DPR Ka-band high sensitivity scans further enhances the DPR sensitivity to upper level cloud, but echo statistics are still not substantially different than TRMM. Utilizing the 16-year TRMM climatology for increased sampling, previously known differences in convection between the EP and WP are confirmed, but they aren’t great enough to justify such a large discrepancy in reanalysis ω profiles. The relationships between Q1 and ω to rainfall statistics in select tropical field campaigns are also investigated. In all cases, the magnitude and height of the peak values of each variable increase with increasing stratiform rain fraction, further suggesting that the EP should have top-heavy rather than bottom-heavy heating and ω because of its higher stratiform rain fraction.

▼ In the East Pacific intertropical convergence zone (ITCZ), Tropical Rainfall Measuring Mission (TRMM) radar-based latent heating retrievals suggest a top-heavy structure; however, the TRMM precipitation radar (PR) underestimates light precipitation (< 0.4 mm h?1) from shallow convection and the low-level latent heating associated with this precipitation. Thus, this study uses observations of stratiform and deep convective precipitation from the TRMM PR and shallow precipitation from the more sensitive CloudSat cloud profiling radar (CPR) to assess the seasonal vertical structure of latent heating in the East Pacific ITCZ for 1998-2015. This study is complemented with three reanalysis datasets (MERRA2, ERA-Interim, and NCEP NCAR) to analyze the meridional circulation changes linked to variations in the ITCZ heating profiles. There is a distinct seasonal cycle in the TRMM/CloudSat latent heating profiles in the East Pacific ITCZ. During DJF, latent heating peaks around 850 hPa because of the predominance of rain from shallow convection. The heating peak rises to 700 hPa during MAM as the contribution from deep convective rain increases along with the presence of a mid-level inflow south the ITCZ. During JJA and SON, stratiform precipitation increases significantly and heating is more equally distributed throughout the troposphere with double peaks at 700 and 400 hPa; the lower peak is related to the strong shallow overturning circulation. In addition, the East Pacific has a meridional slope in latent heating throughout the year as a result of the prevalence of shallow convection in the southern part of the ITCZ and deep convection in the northern part of the ITCZ. This slope is weakest during MAM when a double ITCZ structure exists. Reanalyses only capture certain aspects of this seasonal cycle in the East Pacific ITCZ. While the reanalyses agree that the most bottomheavy heating occurs in DJF and the most top-heavy heating occurs in JJA, they greatly underestimate the amount of heating aloft compared to the satellite retrievals throughout the year. This disagreement has serious implications for how the meridional circulation is captured in this region with reanalyses showing varying ability in representing the shallow meridional circulation and deeper Hadley cell overturning in the East Pacific.

▼ As limitações de dados pontuais para a estimativa da recarga subterrânea em grandes áreas ainda é um grande desafio para uma boa gestão desse recurso hídrico, principalmente em regiões semiáridas. Por causa da escassez de dados observados, a abordagem desta pesquisa estabelece uma integração entre um conjunto de variáveis do balanço hídrico, obtidas a partir de imagens de satélites, para estimar a distribuição espacial da recarga das águas subterrâneas na bacia hidrográfica do rio Ipanema (BHRI), localizada no estado de Pernambuco, Nordeste do Brasil. Os dados de sensoriamento remoto empregados incluem mapas mensais (2011-2012) de precipitação, escoamento superficial e evapotranspiração, utilizados como entradas para a aplicação do método do balanço hídrico (pixel a pixel) em um Sistema de Informação Geográfica (SIG). A precipitação utilizada foi derivada do satélite TRMM (3B43.v7) e seguiu o mesmo padrão médio mensal observado em 15 estações pluviométricas distribuídas pela área de estudo (CC = 0,93 e REQM = 17,1 mm), com estimativas médias anuais de 894,3 (2011) e 300,7 mm (2012). O escoamento superficial, adquirido pelo método SCS-CN a partir de informações dos solos da região e imagem do sensor TM, foi equivalente a 29% da precipitação registrada pelo TRMM durante os dois anos do estudo. Já a evapotranspiração real, obtida pela aplicação do SEBAL em imagens do sensor MODIS, apresentou valores médios anuais de 1.190 (2011) e 1.072 mm (2012). Os resultados do balanço hídrico mostraram que a recarga subterrânea na BHRI apresentou uma grande diferença interanual, caracterizada pelos regimes pluviométricos distintos, com médias de 28,1 (2011) e 4,9 (2012) mm ano-1. Essas recargas foram concentradas principalmente entre os meses de janeiro a julho nas regiões compostas por sedimentos aluviais e outros solos de alta permeabilidade. As aproximações da recarga subterrânea por sensoriamento remoto foram comparadas ao método WTF (Water Table Fluctuation) em uma área específica de aluvião na BHRI. As estimativas realizadas pelas duas metodologias apresentaram boa concordância anual, com valores médios de 154,6 (WTF) e 120,9 (balanço hídrico) mm em 2011, que correspondem a 14,89 e 13,12% das precipitações registradas pelo pluviômetro e pelo TRMM, respectivamente. Para o ano de 2012, apenas a metodologia WTF registrou uma recarga muito baixa de 15,9 mm. Como os estudos referentes ao tema ainda são incipientes, os valores gerados nesta tese fornecem uma boa percepção do potencial do sensoriamento remoto para avaliar as taxas desse importante componente do balanço hídrico na BHRI.

Satellite rainfall estimates have predominantly been used for climate impact studies due to poor rain gauge network in sub-Saharan Africa. However, there are limited microscale studies within the sub-region that have assessed the performance of these satellite products, which is the focus of the present study. This paper therefore considers validation of Tropical Rainfall Measuring Mission (TRMM) and Famine Early Warning System (FEWS) satellite estimates with rain gauge measurements over Ashanti region of Ghana. First, a consistency assessment of the two gauge data products, the Automatic Rain Gauge (ARG) and Ghana Meteorological Agency (GMet) Standard Rain Gauge (SRG) measurements, was performed. This showed a very good agreement with correlation coefficient of 0.99. Secondly, satellite rainfall products from TRMM and FEWS were validated with the two gauge measurements. Validation results showed good agreement with correlation coefficients of 0.6 and 0.7 for TRMM and FEWS with SRG, and 0.87 and 0.86 for TRMM and FEWS with ARG respectively. Probability Of Detection (POD) and Volumetric Hit Index (VHI) were found to be greater than 0.9. Volumetric Critical Success Index (VCSI) was 0.9 and 0.8 for TRMM and FEWS respectively with low False Alarm Ratio (FAR) and insignificant Volumetric Miss Index (VMI). In general, relatively low biases and RMSE values were observed. The biases were less than 1.3 and 0.8 for TRMM and FEWSRFE respectively. These indicate high rainfall detection capabilities of both satellite products. In addition, both TRMM and FEWS were able to capture the onset, peak and cessation of the rainy season, as well as the dry spells. Although TRMM and FEWS sometimes under/overestimated rainfall, they have the potential to be used for agricultural and other hydro-climatic impact studies over the region. The Dynamic Aerosol-Cloud-Chemistry Interactions in West Africa (DACCIWA) project will provide an improved spatial gauge network database over the study area to enhance future validation and other climate impact studies.

▼ Data from multiple satellite and in situ sources are used to investigate the dominant raining cloud populations in the tropics, with the purpose of documenting how diverse the raining cloud populations are at any given time over a scale similar in size to the grid-box (~100 - 200 km) of a present-day global climate model (GCM). For all locations in the tropics, three similar rainfall clusters (defined according to their ensemble of clouds) are found. Differences in mean-state rainfall (e.g. East versus West Pacific Ocean) are largely the result of similar rainfall clusters occurring at ocean basin-dependent relative frequencies of occurrence. Area-average rainfall rates are substantially different for each cluster. While each rainfall cluster is observed in all tropical basins, differing relative frequencies of occurrence imply that rainfall lifecycles (i.e. the time duration for transition from light to deep rainfall) vary as a function of basin. Among the processes influencing this transition, both mesoscale cold pools (inferred from QuikSCAT surface wind field retrievals) and convective inhibition (CIN, derived from radiosonde-observations) emerge as important parameters driving the transition from light rainfall to deep convection at the spatial scale of 100 - 200 km. Associated with significant increases in rainfall are substantial decreases (40%) in convective available potential energy (CAPE). The temporal evolution of rainfall clusters is derived for different lifecycle stages of a composite Madden-Julian Oscillation (MJO) event. It is found that the rainfall cluster consisting of shallow (<3 km) and congestus raining clouds exhibits little temporal variation for all stages of the composite event, while non-raining scenes and deeper clouds are modulated as a function of time for all stages. Instead of a "transition" from shallow to deep convection, the results suggest an "addition" of deep convection at the expense of non-raining scenes. Unique to the initiation stage, deep organized convective systems are rare until 1 - 5 days before the development of a convective anomaly that finally begins propagating eastward. The lack of deep convection during the initiation stage relative to other stages is associated with both decreased values of columnar water vapor (TPW) and increased stability in the lower-troposphere. Both are hypothesized to preclude the development of deeper convection, thus allowing for the slow (10-30 day) increase in TPW by evaporation to continue, in contrast to later stages of the MJO when moisture convergence serves as the largest contributor to moistening. The analyses described above are applied to output from a novel multiscale-modeling framework (MMF) coupled with a slab ocean model. The extent to which the MMF yields results similar to the observational depictions outlined above is discussed in great detail. Advisors/Committee Members: Kummerow, Christian D.

▼ It is estimated that about 60-75 million lightning occur annually, killing an average of 132 people every year in Brazil. The Northeast region of Brazil (NEB) accounts for 18% of the total deaths in the national territory. Considering the population of all Brazilian regions, the state of Piauí presented the highest mortality rate (1.8 deaths per million); which is higher than the country’s total rate (0.8) and the NEB rate (0.5). Studies have shown that lightning formation is associated with the collision between ice particles (crystal and graupel) in the presence of supercooled water droplets in regions with strong updrafts. Therefore, the objective of this study is to evaluate lightning spatial and temporal distribution in NEB, as well as to investigate the relationship between lightning and cloud microphysics, during the period from 1998 to 2013. Data from two orbital plataforms were used: i) Lightning Imaging Sensor (LIS), TRMM Microwave Imager (TMI) and Precipitation Radar (PR) from the Tropical Rainfall Measuring Mission (TRMM) satellite to provide information on the occurrence of total lightning (intracloud and cloud-to-ground) and vertical content of the atmosphere (hydrometeors, precipitation rate, rain type); ii) Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), on board of Terra platform provide the ground elevation data, to verify the influence of topography on lightning rates. The analysis was performed monthly, seasonaly and general spatial distribution . The general spatial distribution was based on Cluster Analysis and aided the identification of the greatest points of lightning occurrence (hotspots). Finally, the lightning was analyzed according to the quantiles technique, finding the characterization according to the microphysical characteristics of clouds. In the NEB territory, it was registered great spatial and temporal variability in the lightning rates, with mean varying from 0 to 44.5 flashs.km-2 .year-1 . All the hotspots are located in Piauí, Maranhão states and west region of Bahia. The topography of NEB seems to act as a facilitator of the convective process, by the increases of intense updrafts formation, an essential factor for the generation of electric charges inside the thunderclouds. The cluster analysis together with the investigation of the characteristics of each of the hostspots allowed to infer that the Intertropical Convergence Zone (ITCZ) and Mesoscale Convective Systems (MCS) are the systems most associated with lightning in NEB territory, being the lightning hotspots characterized as occurrence sites of these systems. Regarding the microphysical parameters of the cloud, it was observed that when the lightning happens, the atmosphere has lower values of liquid water in the cloud, high amounts of ice water, high convective precipitation rate, lift of height freezing level and high probability of precipitation (or the occurrence of this); this information allowed the conceptual model proposition of the microphysical… Advisors/Committee Members: Gonçalves, Weber Andrade (advisor), 04507293464 (advisor), Mattos, Enrique Vieira (advisor), 32575968801 (advisor).

▼ The use of global precipitation datasets such as TRMM, WFD etc. for data scarce regions is gaining popularity since they provide forcing input for hydrological models. They make up for the lack of ground based data or the poor quality of whatever is available in many parts of the world. Using these datasets would be perfect if they were free of errors. Unfortunately, this is not the case. The geo-spatial data obtained from satellites or reanalysis products are not direct measures of precipitation. They are derived from atmospheric parameters such as cloud depth, brightness temperature etc. (Huffman 2007). The conversion of these to precipitation is done using complex algorithms. Efforts are made to calibrate this data but still errors sneak in. Similarly the interpolated gauge data like APHRODITE also has errors because of the inability of interpolation techniques to capture the high spatio-temporal variability in Precipitation. Hence the error estimation of these datasets remains a big problem. Lack of ground based data ensures there is no reference to check these global datasets against. In this research, Triple collocation technique is applied to 3 datasets namely APHRODITE, TRMM and WFD for the river basins in Myanmar. The technique gives an estimate of the residual errors in the 3 datasets (with uncorrelated errors) without using any ground measurements or true values (R. A. Roebeling 2012). This is the first time tit has been used to estimate errors in Precipitation datasets on a daily scale. Though the errors are not absolute, the results give an insight into the relative quality of these datasets. The errors have been calculated in space and time. Hence both temporal and spatial error characteristics are analysed. The study period is from 1998-2001. The results obtained show that for TRMM and WFD, the errors are concentrated and of higher magnitude. For APHRODITE, the errors are more evenly distributed in space. All three datasets showed high errors in the central dry parts and the delta region. Overall, APHRODITE seems to show lowest error values in space. The temporal error characteristics were also different for the 3 datasets. WFD showed highest average and maximum errors. TRMM had some very high error peaks but was in general better than WFD. Looking at the maximum and Average errors, APHRODITE seems to be the best of the three. WFD also shows some error peaks at the onset and end of Monsoon season. This shows its inability to estimate the localized pre and post monsoon storms. The assumption of uncorrelated errors was also verified post analysis. Errors for 2 locations, Bago and Yangon were used to make scatter plots. No strong correlation is visible in the scatter plots reinforcing the assumption that the errors are uncorrelated. The research shows that it is possible to make qualitative and quantitative inferences about the errors in the global precipitation datasets in the absence of in-situ measurements. Based on this research, it is concluded that overall, APHRODITE is the best of the 3 datasets.… Advisors/Committee Members: Van de Giesen, N.C. (mentor).

▼ The objective of this study is to determine the relationship between lightning and six large-scale environmental variables: convective available potential energy (CAPE), normalized CAPE (nCAPE), column saturation fraction (r), 700-hPa omega, 900-700 hPa low-level wind shear (LS) and 900-300 hPa deep wind shear (DS). Lightning data is obtained from the Tropical Rainfall Measuring Mission’s (TRMM) Lightning Imaging Sensor (LIS) from 1998 to 2013 and large-scale environmental variables are derived from 3-hourly Modern-Era Retrospective analysis for Research and Applications version 2 (MERRA-2) data. Each dataset is binned at 0.5° x 0.5°. MERRA-2 data is considered to represent a lightning environment when lightning occurs within 30 minutes of the MERRA-2 time stamp. CAPE, nCAPE and r show clear distinctions in lightning environments compared to non-lightning environments and the largest flash occurrences are associated with lowto- moderate CAPE, moderate nCAPE, slightly negative values of 700-hPa omega (i.e., rising motion), high r, low-to-moderate LS and low DS. Clear geographical distinctions for flash occurrences exist between land and ocean for CAPE, nCAPE and r and between tropical and sub-tropical areas for CAPE, nCAPE, r and DS. The relationship of r with other variables for lightning occurrences is evaluated and it is shown that CAPE and omega with r have the clearest relationships. The association between large-scale environmental variables and lightning is analyzed globally for latitudes between 35°N and 35°S using two statistical models. Using a generalized linear model (GLM), nCAPE and r are the primary predictors for lightning prediction. Using a point-process model, nCAPE is the best predictor, with strong regional contrasts present. The GLM is used in a lightning parameterization to predict lightning from MERRA-2 and the Community Atmosphere Model version 5 (CAM5). Predicted lightning from both datasets generally agrees with observations from the TRMM LIS, which supports the use of a lightning parameterization in GCMs. Advisors/Committee Members: Schumacher, Courtney (advisor), Xu, Yangyang (committee member), Jun, Mikyoung (committee member).
