• Analyzing the modeled evolution of Antarctic sea ice in the current CMIP5 simulations of MPI-ESM.

• Studying the impact of the atmospheric circulation on Antarctic sea ice in the model. More specifically, we assess the impact of the ozone hole and the greenhouse gas increase on the atmospheric circulation and thus on the sea ice by perfoming model experiments. We are trying to understand the observed and modeled long-term changes of the Southern Ocean sea ice and to determine the external drivers and internal processes. This work is carried out in collaboration with the working group "Middle and Upper Atmosphere".

In my Master's thesis I have studied the impact that variations in the wind field in the Antarctic atmospheric boundary layer have on sea ice. In particular, I was interested in the meridional wind-driven ice transport and how its variability influences the regional sea ice cover. In order to investigate this relation, I have analyzed data from a regional atmospheric climate model and satellite observations in the period 1989 to 2005.
