▼ Snow is a common overlying surface during winter-time and the redistribution of snow by wind is a very important concept for any hydrological research project located within the cryosphere. Wind redistributes snow by eroding it from areas of high wind speed, such as ridge tops and windward slopes, and deposits it in areas of lower wind speeds, such as the lees of ridge tops, vegetation stands, and topographic depressions. The accurate modelling of blowing snow processes such as erosion, deposition, and sublimation have proven to be rather problematic. The largest issue that many modellers must deal with is the accurate collection of solid precipitation throughout the winter season. Without this, incorrect energy and mass balances can occur. This thesis makes use of a new method of acquiring solid precipitation values through the use of an SR50a ultrasonic snow depth sensor and then incorporates it into a version of the Cold Regions Hydrological Model (CRHM) which includes the Prairie Blowing Snow Model (PBSM) and the Minimal Snowmelt Model (MSM) modules. The model is used to simulate seasonal snow depth over an agricultural field in southern Ontario, Canada and is driven with half-hourly locally acquired meteorological data for 83 days during the 2008-2009 winter season. Semi-automated snow surveys are conducted throughout the winter season and the collected in situ snow depth values are compared to the simulated snow depth values at multiple scales. Two modelling approaches are taken to temporally and spatially test model performance. A lumped approach tests the model‟s ability to simulate snow depth from a small point scale and from a larger field scale. A distributed approach separates the entire field site into three hydrological response units (HRUs) and tests the model‟s ability to spatially discretize at the field scale. HRUs are differentiated by varying vegetation heights throughout the field site. Temporal analysis compares the simulated results to each day of snow survey and for the entire field season. Model performance is statistically analyzed through the use of a Root Mean Square Difference (RMSD), Nash-Sutcliffe coefficient (NS), and Model Bias (MB). Both the lumped and distributed modelling approaches fail to simulate the early on-set of snow but once the snow-holding capacities are reached within the field site the model does well to simulate the average snow depth during the latter few days of snow survey as well as throughout the entire field season. Several model limitations are present which prevent the model from incorporating the scaling effects of topography, vegetation, and man-made objects as well as the effects from certain energy fluxes. These limitations are discussed further.

▼ A study was conducted to compare snow accumulation and melt during rainfall in adjacent forest and clearcut plots in the transient snow zone of the western Cascade Range in Oregon. Snow accumulation differences were determined by comparing the water equivalents of forest and clearcut snowpacks. During rain-on-snow periods, energy balances were analyzed to evaluate the differences in energy transfers acting to melt snow in the two plots. In this way, snowmelt differences can be linked to the microclimatic alterations related to clearcut logging. Snowmelt estimated by energy balace analyses was compared with snowmelt determined by snowmelt lysimeter data and snow survey information. The forest canopy played a strong role in controlling snow accumulation. Snow trapped in the forest canopy melted faster than snow that accumulated on the ground in the clearcut plot. Snow survey information indicated that the water equivalents of clearcut snowpacks averaged 29 mm, but were up to 74 mm greater than forest snowpacks. For five rain-on-snow events during the winter of 1983-1984, four of which rainfall amounts were smaller than that called for in the study design, a comparison of snowmelt estimated by the three methods had variable results. Only during the last two rain-on-snow events, of which one was the annual rainfall event, did results from the three methods all show greater snowmelt in the clearcut plot. Snowmelt determined by lysimeter information was more reliable during these events than the previous three events because of improved rainfall sampling. Snowmelt estimated by energy balance analyses was consistently greater in the clearcut plot. Longwave radiation was the greatest source of snowmelt for all events, contributing 38-88 percent of the total computed snowmelt of each event. Snowmelt attributed to net longwave radiation was 22-56 percent greater in the clearcut plot. However, the combined fluxes of latent and sensible heats accounted for a large portion of the snowmelt differential between the plots. Although the combined fluxes ranked second in importance as a source of heat for snowmelt (6-36 percent of the total snowmelt for each event), in the clearcut plot they were 226-300 percent of the combined fluxes in the forest plot. During the largest rain-on-snow event (February 11-13, 1984), total snowmelt was 55-111 percent greater in the clearcut plot depending on the method of measurement. The increased snowmelt of the clearcut plot is attributed to (1) greater snow accumulation prior to the event and (2) greater energy inputs during the event.

▼ Faceted snow crystals develop at or near the snow surface due to temperature gradients. After burial, snow avalanches regularly fail on these layers. Generally, surface hoar deposits when the snow surface is cooler than the surrounding environment; near-surface facets form when the subsurface is warmed by solar radiation and the surface is cooled by radiative, convective, and latent heat exchange. Field research stations were established that included daily observations and meteorological data. In two seasons, 14 surface hoar and 26 near-surface facet events were recorded. Statistical analysis of the surface hoar events indicated three factors that were related to surface hoar growth: incoming long-wave radiation, snow surface temperature, and relative humidity. The ideal conditions for each of these parameters were 190-270 W/m², -22 to -11°C, and 45-80%, respectively. For near-surface facet formation, long- and short-wave radiation and relative humidity were statistically linked to the events. The ideal conditions for these parameters ranged from 380-710 W/m², 210-240 W/m², and 23-67%, respectively. Using a thermal model, sensitivity analysis, and Monte Carlo simulations the conditions that lead to facet formation were explored. Based on computed mass-flux, the formation of surface hoar was mainly driven by changes in long-wave radiation, air temperature, wind velocity, and relative humidity. From these terms graphical tools were developed to predict surface hoar; the numerical results matched reasonably well with the field observations. Based on the presence of a specific temperature gradient understood to lead to near-surface facets, three terms were determined to be the most influential: density, thermal conductivity, and incoming long-wave radiation. Using these terms, albedo, and incoming short-wave radiation – a requirement for radiation-recrystallization – a means for predicting the presence of near-surface facets was presented. The physical and analytical data presented indicates that incoming long-wave radiation is the most influential parameter governing the conditions that lead to surface hoar and near-surface facet growth. The analysis suggests that snow with low density and high thermal conductivity may be conducive to the formation of near-surface facets.

▼ Snowbands can produce locally larger snowfall accumulations as well as reductions in visibility thereby being hazardous to vehicles and aircraft. The study herein is the first to combine multi-Doppler retrieved winds, in situ snow crystal size distributions, and polarimetric radar variables within snowbands for two radar wavelengths. Data includes two polarimetric radars: Doppler on Wheels (DOW) – a mobile X-band polarimetric Doppler weather radar – and the University of North Dakota (UND) polarimetric C-band radar (hereafter: “UND radar”). Also used in this study are data from the two-dimensional cloud (2DC) probe attached to the UND’s Citation II weather research aircraft. Retrieved wind velocities, from dual-Doppler analysis, and dual polarization radar variables, are matched to the aircraft’s transect location and 2DC probe images inside and outside the snowband. Regarding kinematics, upward motion in both the retrieved vertical wind and aircraft-measured winds is seen generally west of the DOW location with downward motion generally east. The dual-Doppler retrieved horizontal winds also show easterly flow at lower altitudes and westerly at higher altitudes, consistent with a sounding from Bismarck, ND. These wind patterns are generally persistent in the local environment regardless of the snowband’s presence. Ice hydrometeors, measured by the 2DC probe, are more numerous and larger inside the snowband, compared to a weaker-reflectivity snow-filled region outside the snowband. These differences in number concentrations are present at all altitudes sampled but are most distinct at higher altitudes. Along the aircraft transects, both radars observe larger average KDP values (most altitudes) and larger average HV values (all altitudes) inside the snowband. Differences exist between the same radar variable for near-simultaneous dual radar measurements. These differences are: greater reflectivity (regardless of altitude and location) for DOW compared UND, greater average HV for the DOW radar compared to UND, closer-to-0 dB average ZDR values for DOW inside the snowband, and closer-to-0 dB average ZDR values for UND outside the snowband. These radar variable differences could be related to calibration and wavelength differences between the DOW and UND, slight differences in the sampling area, and small scale variability within the snowband. Radar reflectivity (greater values inside the snowband) and ZDR (values closer to 0 dB inside the snowband) are consistent with the original hypothesis. However vertical velocity has similar values both inside and outside the snowband. Stronger radar reflectivity and ZDR closer to 0 dB do not coincide with stronger updrafts inside the snowband. This snowband had unique polarimetric and hydrometeor size distribution characteristics compared to its surroundings. The characteristics inside and outside the snowbands determined from this study, could be used to improve the… Advisors/Committee Members: Matthew Gilmore.

▼ The goal of this research has been to build upon previous studies focused on what processes control the distribution of snow water equivalent (SWE) in alpine environments. This involved taking a comprehensive look at the widely accepted physiographic variables of: elevation, slope, aspect, solar radiation, and wind exposure, but also avalanche activity, which has been given limited explicit inclusion. The paired basin comparison adopted in this study, between a hypothesized avalanche prone basin and avalanche free basin, has been previously used to correlate avalanche activity with snowmelt runoff. However, it has not been used in an attempt to parse out which variables have the dominant influence on SWE distribution between adjacent areas of very similar physiographic character. While most previous studies have focused on the period of peak SWE to study this distribution, this current research looked at the evolution of the controlling variables throughout snowpack development. A robust dataset of snow depth and SWE measurements were collected during a January 31 - July 10, 2013 field campaign on Cedar Mountain near Big Sky, MT. Physiographic variable values were extracted from a 10 m resolution digital elevation model (DEM) at snow sample points and input as predictors of observed SWE in multiple linear regression (MLR) and binary regression tree (BRT) models to estimate SWE across the study area. Optimal models were selected by various measures of goodness of fit and cross-validation criteria. Calculated R 2 values for MLR models (0.17-0.57) and BRT models (0.33-0.66) were comparable to previous studies indicating a relative level of success in predictive performance. Subsequent analysis of each optimal model's variable selection and predicted SWE distributions revealed differences in the spatial and temporal patterns of this metric between the paired basins, confirming some well-understood processes as well as offering new insights.

In the recent past, there are indications of changes in the surface air temperature, extreme weather events, snow and Indian summer monsoon. This thesis analyses the above weather phenomena based on observed data and climate model simulations for the present as well as the near future. Earlier studies show a strong negative relationship between Eurasian snow cover/depth and Indian summer monsoon rainfall. Limitations of such studies are that both the parameters snow and rainfall were seasonally averaged over large areas. Indian summer monsoon has its own characteristics of evolution such as onset, active, break and withdrawal phases which have been studied extensively. However, the evolution of Eurasian snow is yet to be examined. Further, it is interesting to explore the characteristics of evolution of snow over the different regions of Eurasia and their relationship with the evolution characteristics of summer monsoon. In this thesis, a detailed examination has been done on the starting and the ending dates of snowfall over different regions of Eurasia and attempts have been made to explore any relationship with onset of Indian summer monsoon. It is observed that the regions where snowfall starts early, it ends late. Further, in those regions maximum snow depth also occurs late. In some years, more snowfall in East Eurasia is followed by less snowfall in West Eurasia. Also snow depths particularly in the northernmost and southwest regions of East Eurasia are opposite in phase. The results of this study indicate a weak relationship between snow starting dates in Eurasia and summer monsoon onset dates in the Kerala coast. However, the relationship between the northernmost Eurasian snow depth and the summer monsoon precipitation in the Peninsular India is significant. Today, regional weather/climate models are increasingly used to study several atmospheric phenomena. The Regional Climate Model, RegCM3 has been successfully integrated to simulate the salient features of Indian summer monsoon circulation and rainfall. In this thesis, multi-member simulations are performed to identify and remove the systematic errors in the model. Changes in the frequency of extreme rainfall events simulated by RegCM3 are also examined. RegCM3 has well simulated rainfall over the Central India. Dry bias is observed over Central India and wet over Northwest and Peninsular India. Shift in mean sea level pressure is observed over the foothills of the Himalayas and Tibet.

▼ Hydrologists and water managers have been attempting to accurately estimate watershed scale snow water equivalent (SWE) for over a century. Extensive monitoring networks, remote sensing technology, and sophisticated modeling approaches have greatly improved these estimates; however, water inputs from snow in mountainous areas are still subject to considerable uncertainty due to SWE spatial variability. In an attempt to improve the understanding of physical processes and controls influencing SWE spatial variability, a field campaign to measure the spatial and temporal distribution of SWE within the Dry Creek Experimental Watershed (DCEW) was conducted during 2009 and 2010. These measurements are compared to a distributed SWE data assimilation and modeling product from the National Weather Service called the Snow Data Assimilation System (SNODAS) to estimate the sub-pixel variability and accuracy of the model estimates, as well as attempt to understand model deviation from observed conditions. These data are evaluated using the variogram to assess the evolution of SWE variability and spatial correlation lengths throughout the winter. Correlations between snow depth and landscape characteristics are explored to determine the most influential physical processes influencing SWE distribution. Specifically, this work indentifies the relative importance of differential accumulation, redistribution, and differential ablation at three spatial scales. Results from this work indicate that at the watershed scale (27 km2), elevation is the most important control on snow distribution, while at the SNODAS pixel scale (1 km2), and 1 meter spaced transect scale, differential solar radiation is a stronger control on SWE distribution during ablation. Comparison of transect scale and SNODAS pixel scale observations with SNODAS show the model under-predicts SWE throughout the winter at two out of three sites, and over-predicts during ablation at one site. SNODAS captures the watershed scale elevation trend, but under-predicts the magnitude of SWE at assumed maximum accumulation.

▼ Snow loads account for a majority of roof damage and associated losses in the United States. The significant impact that snow related failures can have on the safety of people and the economic losses associated with business closures and repair costs make the design and mitigation of snow related failures very important. The purpose of this thesis is to develop models to predict roof snow loads, for use in performance-based engineering. Performance-based snow engineering can provide decision makers with a better, quantitative understanding of snow related risks. Two probabilistic models were developed to have an understanding of the factors that affect the magnitude and distribution of roof snow load. The models developed are different from building codes and standards, where the model predicts the roof snow load for a single snow event instead of a 50-year maximum roof snow load used in design standards. The first model predicts uniform roof snow loads, given a ground snow load and roof characteristics; the second model predicts non-uniform drifting snow loads for multilevel roofs, given ground snow load, ground snow density and roof characteristics. Ground snow load hazard curves, or predictions of the probability that a specified ground snow load level will be exceeded in a particular year, are available from weather data. The probabilistic load models can be used in a performance-based engineering framework to predict the likelihood that certain critical deflections or stresses will be exceeded. In this study, the models are used to predict deflections and stresses in an open walkway roof structure. Hazard curves were developed to show the probability of exceedance of a critical deflection for different ground snow loads. Hazard curves of this type can be used in analysis of other light-weight steel structures to develop metrics of structural failure and collapse that can help building owners decide whether to invest in retrofitting roofs.

▼ Mountain snowpacks act as seasonal reservoirs, providing a critical water resource to ~1.2 billion people globally. Regions with persistent snowpacks (e.g., mountain and polar environments) are responding quickly to climate change and are warming at faster rates than low-elevation temperate and equatorial regions. Since 1915, snow water equivalent (SWE) in the western U.S. snowpack has declined by 21% and snow covered area is contracting in the Rocky Mountains. Despite the clear importance of this resource and the identification of changes affecting it, no current remote sensing approach can accurately measure SWE at high spactiotemporal resolution. L-band (1-2 GHz) Interferometric Synthetic Aperture Radar (InSAR) is a promising approach for detecting changes in SWE at high spatiotemporal resolution in complex topography, but there are uncertainties regarding its performance, particularly when liquid water content (LWC) is present in the snowpack. LWC exhibits high spatial variability, causing spatially varying radar velocity that introduces significant uncertainty in SWE-retrievals. The objectives of this thesis include: (1) examine the importance of slope, aspect, canopy cover, and air temperature in the development of LWC in a continental seasonal snowpack using 1 GHz ground-penetrating radar (GPR), a proxy for L-band InSAR, and (2) quantify the uncertainty in L-band radar SWE-retrievals in wet-snow. This research was performed at Cameron Pass, a high elevation pass (3120 m) located in north-central Colorado, over the course of multiple survey dates during the melt season of 2019. Transects were chosen which represent a range in slope, aspect and canopy cover. Slope and aspect were simplified using the northness index (NI). Canopy cover was quantified using the leaf area index (LAI). Positive degree days (PDD) was used to represent available melt-energy from air temperature. The spatiotemporal development of LWC was studied along the transects using GPR, probed depths, and snowpit measured density. A subset of this project substituted Terrestrial LiDAR Scans (TLS) for probed depths. Surveys (17 in total, up to 3 surveys per date) were performed on seven dates which began on5 April 2019, where LWC values were ~0 vol. %, and ended on 19 June 2019 where LWC values exceeded 10 vol. %. Point measurements of LWC were observed to change (ΔLWC) by +9 vol. % or -8 vol. % over the course of a single day, but median ΔLWC were ~0 vol. % or slightly negative. LAI was negatively correlated with LWC for 13 out of the 17 surveys. NI was negatively correlated with LWC for 10 out of the 17 surveys. Multi-variable linear regressions to estimate ΔLWC identified several statistically significant variables (p-value < 0.10): LAI, NI, ΔPDD, and NI x ΔPDD. Snow-on Terrestrial LiDAR Scans (TLS) were conducted twice during the melt season, and a snow-off scan was conducted in late summer. Snow-on scans were differenced from the snow-off scan to produce distributed snow depth maps. TLS-derived snow depths compared poorly with probe-derived… Advisors/Committee Members: McGrath, Daniel (advisor), Fassnacht, Steven (committee member), Rasmussen, Kristen (committee member).

▼ Seasonal snow cover over the Tibetan Plateau (TP) is an important indicator of the mean conditions of temperature and precipitation in the area and its surroundings. However, the assessment of snow cover variability over the TP has been a challenging problem due to lack of conventional observations. High-resolution snow mapping products acquired from the Moderate Resolution Imaging Spectroradiometer (MODIS) on the NASA Terra spacecraft have provided an excellent opportunity to define details in the spatial and temporal snow cover distribution in the area. In this study, the accuracy of MODIS/Terra snow cover data is first evaluated by comparing the data with in situ Chinese station snow observations; results show that the overall accuracy of MODIS snow data is about 90% over the TP. Statistical analysis is then performed to explore the distribution and variability of snow cover based on the available data from 2000-2006. It was found that the most persistent snow cover is located in t h e southern and western edges of the TP, especially large mountain ridges and the western part of Yarlung Zangbo Valley. The higher snow cover fractions (SCFs) are largely concentrated in the regions where the elevation is higher than 6000m. The snow persistence varies in different elevation ranges and generally becomes longer with increases in the terrain elevation. In addition, the spatial distribution of the snow cover not only depends on the elevation, but also varies with the terrain features (e.g., aspects, slopes etc.) in the local areas. With 7-year observational data, seasonal and interannual variability of snow cover has been detected, but the persistence of the seasonal and interannual anomalies in snow cover is generally lacking due to the small sample of data available. There are slight decreasing trends in SFCs over the TP during 2000-2006. With the MODIS satellite snow cover fraction data during 2000-2006, and NCEP/DOE reanalysis 2 dataset, the relationship between snow cover anomalies over the TP and the East Asian summer monsoon (EASM) is examined. It is found that the onset of EASM is well associated with snow cover anomalies in spring. Specifically, positive or negative snow cover anomalies are followed by a later or earlier onset of EASM, respectively. The strength of EASM shows a weak connection with snow cover anomalies with fewer exceptions. Based on a previous conceptual model, physical mechanisms associated with this snow-monsoon connection are discussed.
