%X In Part I of this study, the circulation and weather systems of two severe hot weather cases that occurred in June and July 1999 have been analyzed In this paper (Part II), mesoscale model (MM5) developed by Penn/NCAR was used to simulate the two cases Simulation results were used to analyze the physical mechanism of the severe hot weather The results showed that the model can simulate the land subtropical-over high of two cases and its moving, intensity and coverage for a long time successfully if nudging assimilation was used The main reasons of forming severe hot weather were the downdraft of land subtropical-over high and solar radiation
