The new weather forecasting model for the Alpine region

Today, the Federal Office of Meteorology and Climatology MeteoSwiss puts the new high-resolution forecasting model COSMO-1 into operation, which runs on the supercomputer “Piz Kesch” operated by CSCS (Swiss National Supercomputing Centre). The grid spacing of this eight-times-a-day simulation is 1.1 km. This means double the resolution of the old forecasting model COSMO-2, in use since 2008 - an important improvement for the prediction of local weather events such as thunderstorms, thermal wind systems or the Foehn effect.
