A Nowcasting Method of the Heavy Precipitation by means of Satellite and Radar Data

Based on the short-range forecasting, the meteorological satellite infrared digital data was quantitatively processed and statistically analysed,the rainfall estimation was given. According to the motion and propagating feature of the precipitaton cloud systems,combined with the weather system classification and the radar echo data,a 0 — 3 hours nowcasting method of the heavy precipitation was described. It may be used to forecast rainfall in the regions of the Miyun Reservoir of Beijing and upper reaches of Chao River and Bai River.
