AROME is a small scale numerical prediction model, operational at Meteo-France since December 2008. It was designed to improve short range forecasts of severe events such as intense Mediterranean precipitations (Cévenole events), severe storms, fog, urban heat during heat waves. AROME was developed in close collaboration with national and international institutes so as to benefit from the latest research in atmospheric modelling. The physical parametrizations of the model come mostly from the research Méso-NH model whereas the dynamic core is the Non-Hydrostratic ALADIN one. The size of the mesh, many time smaller than previous model, is 1.3km against 7.5km for ARPEGE over France. The model is initialized from data assimilation derived from the ARPEGE-IFS variational assimilation system and adapted to the AROME finer resolution. Besides available data from ARPEGE, AROME is supplied, for instance, by precise data from the ARAMIS radar network (doppler wind and precipitation), assimilated on an hourly basis.
