Meteorological evaluation of the OpenIFS outputs is demonstrated here on case studies. Two weather events have been chosen in order to show the OpenIFS model 's capabilities on the one hand, and on the other hand, to provide reference cases for the users (to compare the results of their installed model version with the ones run at ECMWF or to inter-compare the results of different model versions). Important aspects at selection of the cases were their geographical scope and their physical background, i.e., the focus was on those storm events which had severe impact over Europe and were governed by large-scale dynamical forcings. Cases both with weak and good operational ECMWF IFS forecast skill were considered. Several model experiments were carried out and the model outputs are visualized using Metview.

After introduction of the weather events, this page guides the user step by step on running the selected experiment, post-processing the model outputs, downloading the reference data and visualization the outcomes with Metview. The input data and namelists neccessary for the model runs, the scripts for MARS retrieves and Metview macros for visualization are available in the OpenIFS repository and can be downloaded.
