The contributions of different weather systems to rainfall are calculated, the relationship between the rainfall and the characters of the spatial and temporal distributions of rain clouds is analyzed. Then, the rainfall differences in urban, mountainous and plain areas are also studied. The results show more rainfall were observed from 1990 to 1999 than that from1980 to 1989. The main reason is the increase of convective rainfall due to cyclone activities. The regional precipitation differences show that the urban area has more rainfall than the mountainous area.
