Reporting year 2020 Project Title : High-impact precipitation events prediction with convection-permitting models nested in the ECMWF ensemble : new tests with the MOLOCH and Meso-NH models Computer Project Account :

It is demonstrated how the model simulation speed has the largest impact on a joint evaluation with the model performance because the accuracy of the three limited-area ensembles, amplifying the forecasting capability of the global predictions, does not differ substantially.
