Confronto tra osservazioni meteorologiche radar e uscite di un modello NWP di una forte grandinata a Torino, Italia

In this study I have used the weather Research and Forecasting (WRF ) model to simulate the features of a severe thunderstorm that hits the northwest Italy on 24 August 2013. I've used the WRF model with three nested domains with a resolution of 27 km,9 km and 3 km respectively. I've used two double moment microphysical schemes (Milbrandt and Morrison) with convective parameterizations,BMJ scheme and explicit alternatively. The model has been integrated for 24 h, from 00.00 UTC of 24 August 2013 to 00.00 UTC of 25 August 2013 and with the ECMWF initial conditions. The simulations without convective parameterizations show more storm cell than that observed. All the simulations predict the thunderstorm an hour before circa. The best simulation resulted that with Morrison microphysical scheme and with convective parameterization.
