The consideration of North and Baltic Seas in regional climate modelling with the coupled atmosphere-ocean-ice model COSMO-CLM/NEMO
The main objective of this PhD work is to assess the impact of fine-scale air-sea interaction on the performance of a regional climate prediction model in marginal sea regions. Focus is on the North and Baltic Seas, the largest marginal sea area in the mid-latitudes. Motivation for this work is to b...
