Climate System Research Group
Our research targets the physical processes that control interactions and linkages between different “bricks” of the climate system.
In doing so, a central theme is the relation between the cryosphere (snow and ice) in high mountains and the large-scale mechanisms in the climate. To decipher this relation various “players” are of interest: coupled atmosphere-ocean modes acting over thousands of kilometers; associated flows in the atmosphere which are strongly modified by high mountains over land; and the meteorological conditions in the mountains which provide the local environment for glacier variability.
More knowledge of the causal link between these components holds great potential to better understand the functioning of our climate system – through different space/time dimensions and from the surface up to higher air layers (the mid troposphere). This vitally extends the basis for improving climate projections for the future.
