Abstract This document presents recent verification statistics and evaluations of ECMWF forecasts. Recent changes to the data assimilation/forecasting and post-processing system are summarised in Section 2. Verification results of the medium-range free atmosphere ECMWF forecasts are presented in Section 3, including, when available, a comparison of ECMWF forecast performance with that of other global forecasting centres. Section 4 deals with the verification of ECMWF forecasts of weather parameters and ocean waves, while severe weather events are addressed in Section 5. Finally, Section 6 provides insights into the performance of monthly and seasonal forecast systems. A short technical note describing the scores used in this report is given in Annex A.
