Testing of WRF parameterizations with X-band radar data in a convective rainfall event.

During vegetative season, crops may be damaged by intense rainfall events, such as thunderstorms. In order to limit the risks and to issue thunderstorm warnings, an accurate weather forecast is indispensable. Since the storms occur in limited time and space scales, their forecast is not simple. In this work, the meteorological model WRF was used to simulate convective precipitation associated with an event occurred on 2 nd July 2012 in Turin (Italy), and to examine its sensitivity to different schemes of microphysics and clouds parameterization. The precipitation was simulated with 1 km resolution and compared with the observations gathered from a high-resolution X-band radar, operating in the same area during the event.
