The main adaptation being to perform an analysis every hour instead of every 3 hours. To avoid the difficulties linked with 1 hour cycling, for the time being, we only carry out the analysis stage with a first guess file taken from another model. Results from this model will be shown.The second part of this talk will focus on a sub-version of this AROME-nowcasting model, so called AROME-airport. This AROME-airport model will be used on a specific dedicated area (CDG airport in Paris) in order to assess the potential gain of such configuration. This model will provide an input to a Wake-Vortex forecast model. The main goal of this version is to add dedicated new observations, and mainly to have a 500m gridsize model run on a short time compatible with nowcasting forecast leading time. With AROME-airport we will try to understand the potential gain of having a higher resolution forecast through diagnostics such as wind, turbulent kinetic energy or eddy dissipation rate.</font></font></p>
