Local climatic phenomena, such as glaciers, lakes, or vegetation patterns, always show a certain dependency on the properties of large-scale climate. On a day-to-day basis, these properties are manifested as a sequence of weather types, which enclose characteristic distributions of high- and low-pressure systems over Europe and the associated weather conditions. Subproject “Climate Dynamics” will establish the local effects of weather types for Bavaria over several decades with the help of an atmospheric (computational) model, which will be executed on high-performance systems (so-called “supercomputers”).
Complementary steps will allow us to interpret the results for the recent past (e.g., 1981-2010) as well as for the expected climatic conditions in the 21st century. In particular, these steps will help to assess ecologically important elements like air temperature and precipitation in the context of extreme events. The subproject, therefore, will deliver the physical, meteorological basis for the understanding of weather type effects on selected forest sites in Bavaria. Since people usually have a strong association with weather types, which springs for instance from the daily weather reports in the media, a good connecting point to educational research on climate change impacts emerges as well.
