2. Spiegl, Tobias Christian. Effects of a potential Grand Solar Minimum on the climate system against the background of anthropogenic climate change.

Degree: 2017, Freie Universität Berlin

The long-lasting minimum of Solar Cycle 23 as well as the overall weak maximum of Cycle 24, reveal the possibility for a return to Grand Solar Minimum conditions within the next three to five decades. The past millennium featured at least 5 excursions (lasting 60–100 years) of exceptionally low solar activity, induced by a weak magnetic field of the Sun. The last Grand Solar Minimum, the so called Maunder Minimum (1645–1715), coincides with the ’Little Ice Age’ in Europe, a time of severe cold, especially during winter season. The quantification of the implications of such a projected decrease in solar forcing is of ultimate importance, given the on-going public discussion of the role of carbon dioxide emissions for global warming, and the possible role a cooling due to decreasing solar activity could be ascribed to. Since the magnitude of a future reduction in solar forcing, due to a possible Grand Solar Minimum, is highly uncertain, 3 different solar reconstruction datasets for the Maunder Minimum period that show significant differences in both, TSI (total solar irradiance) and SSI (solar spectral irradiance), were used to simulate a future Grand Solar Minimum under RCP6.0 conditions. All transient simulations were carried out using the ocean-coupled chemistry-climate model EMAC-O. Besides interactive ozone chemistry and a high model top (0.01 hPa) the model includes a high-resolution shortwave radiation scheme. The results obtained, suggest a certain slowdown of global-scale temperature increase mainly during the core period of a future Grand Solar Minimum. However, some regions show a rather strong response to Grand Solar Minimum conditions. These include the high latitudes of the Northern Hemisphere, but also vast areas of the inner tropics. Furthermore it shows, that a Grand Solar Minimum might be associated with a modulation of the ENSO amplitude which faces less amplification during the 21st century under reduced solar forcing compared to the reference simulation. In the middle atmospere a Grand Solar Minimum might reinforce the expected cooling due to rising greenhouse gas emissions. This additional cooling can be attributed to reduced short wave radiation during a Grand Solar Minimum, less ozone production and an associated decrease in short wave heating rates. It also can be shown that a Grand Solar Minimum interferes with a recovery of total column ozone, which is markedly delayed under the influence of a Grand Solar Minimum. Conclusively, a distinct influence on middle atmosphere dynamics in Northern Hemisphere winter was found under Grand Solar Minimum conditions. These solar induced changes are characterized by a weakening of the polar vortex, more frequent sudden stratospheric warmings in early winter and a top-down modulation of tropospheric winter variability.
