Application of Meteorological Satellite Data for Forecasting Medium-range (3—5 days) Rain Storm over the Changjiang River

This paper presents three kinds of evolutionary cloud patterns summarized from GMS images and two kinds of OLR pentad mean fields from POS for the mediumrange rain storm prediction over the upstream reaches of Changjiang river based on the analysis of all eleven cases in the summers from 1978 through 1987. It is revealed that the interaction among the cloud systems of synoptic scales even larger scales over the middle or lower latitude areas is very important condition. In addition, in order to verify the mentioned above, we used the severe rain data in early July 1989. The results are satisfactory
