COSMO-2 Model Performance in Forecasting Foehn: a Systematic Process-oriented Verification

Strong foehn episodes can develop into violent wind storms capable of causing severe material damages. Accurate forecasts of foehn strength and duration are essential for preventative and protective measures against losses to be effectively taken. High-resolution numerical prediction models, such as COSMO-2, show several deficiencies when forecasting both south foehn episodes in the Swiss Alps
