The study of case operation MMS Model to simulate rain resulted from convection

Due to its complexity and destructive nature, convection has been subject of many studies and researches among weather phenomena throughout the world. Scientists have attempted for decades to generate different types of models to provide the possibility of abating or, at least, reducing convective weather phenomena effects on people’s lives. In south or southwest of Iran, people are familiar with convective phenomena and their effects. Due to socio-economic importance of convective phenomena and availability of a meso-scale (MM5) model in Iranian Meteorological Organization, it has been tried to investigate the ability of the model to simulate and to predict convective precipitation in south and southwest of the country. The results of the study show that the model produces acceptable results on convection that arises from sharp baroclinic, but it has failed to produce acceptable results where convection is due to local conditions.
