| Abstract: | In this paper, the satelLite images character of rainfall is analysed. Some factors being relation to rainfall are found, such as cloud top temperature, variable of cloud top temperature and satellite images for vaper chanel. A model of estimdting rain amount from satelLite images is made out. The model is used from May to Augest in 1998, the results are quite good at the ralnfall estimation. |
