Research interests

  • Combining Observations and Models of atmospheric processes
  • Evaluation challenges for a new generation of km-scale global models
  • Mathematical modelling of clouds on all scales (from high-resolution large-eddy simulations up to global climate models)
  • Influence of microphysical processes on the dynamic and organization of clouds
  • Cloud parameterizations in global climate models
  • Mathematical description of various processes in the atmosphere and their interaction

Projects

  • C3SAR (DFG research unit Cloud Structure & Climate - Closing the 3D Gap) -  Modelling cloud micro- and macrophysical properties and their radiative effects
  • (AC)3: Arctic Amplification: Climate Relevant Atmospheric and Surface Processes and Feedback Mechanisms (DFG)
  • WarmWorld: Exascale Earth System Models to anticipate changes in a Warmer World (BMBF)
  • HALO-(AC)3 (HALO-SPP): Understanding clouds and precipitation at the sub kilometer scale using HALO and ICON - Air mass transformations in the Arctic (UCP-Arctic) (DFG)
