Methods to test the performance of a restricted area physical-mathematical model with variation of the physical parameterization of convective phenomena

In the restricted area physical-mathematical models, the physical parameterization of convective phenomena plays a key role. In this work, the extreme weather event of 25th November 2016, occurring in Sicily, is considered as case of study. The heavy rainfalls recorded in this event were caused by cloudy systems of convective nature. For this reason, the performance of the restricted area physical-mathematical model, optimized for complex orography areas, has been tested varying the physical parameters of the convective phenomena. Performance were evaluated using appropriate verification methods.
