AbstractThis 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, oceanic waves and severe weather events. Finally, Section 5 provides insights into the performance of extended range forecast systems. A short technical note describing the scores used in this report is given.
