Abstract

In the framework of an integrated modeling approach at regional and local scale, some models have been implemented and run in our institution: the SISL-MSM by us, the MESO-NH by the Laboratoire de Aerologie and Meteo-France, the ETA Model by NCEP, the MC2 model by CMC-Environment Canada and the WRF model (by many agencies). Boundary conditions are provided by our ESM (European Spectral Model) which is nested in our GSS (Global Simulation System), a global model and an ensemble prediction system. A case study of a summer thunderstorm in the south-alpine region is presented, with simulation made by different models and grid mesh sizes in the same area. Observational data have been compared to the model simulations. The comparison shows the differences among the models and simulation designs in the complex topography of the Alps, the characteristics of the atmosphere behaviour in mountain regions and the importance of non-hydrostatic effects to correctly reproduce the overall physics and dynamics at the mesoscale.
