Luise Schulte is a researcher at ECMWF and a PhD candidate at the University of Cologne (Germany). She is part of the STEP UP! fellowship program by the German Weather Service (DWD) and the project is associated with the Transregional Collaborative Research Center “ArctiC Amplification: Climate Relevant Atmospheric and SurfaCe Processes, and Feedback Mechanisms (AC)3”.

Her research focusses on the representation of Arctic mixed-phase clouds in the ECMWF model IFS, which includes model evaluation based on (remote sensing) observations and sensitivity tests in single-column and full global model runs, with the goal of improving cloud representation and finally surface radiation in the model.

The work presented at EGU24 highlights model deficiencies in the representation of cloud liquid water in the central Arctic during the MOSAiC campaign with opposite model errors in summer and winter. Detailed sensitivity tests in a single column model setup show a strong sensitivity to uncertain microphysical processes in winter. The work informs model development towards an improved representation of mixed-phase microphysics, with the potential to have a large impact on modelled surface radiation.
