Based on the weather data from year 1988 to 1997, 71 cases of hail weather processes in Chifeng, Inner Mongolia are analyzed, and four circulation patterns for the hail weather process are concluded. And physics parameters about convection are calculated using some recent research results. Subsequently, the prediction factors which have reliable and stable physics are sifted and an integrated prediction method is developed for the local hail process, and the application effect is better.
