摘　　要：在短期和短时天气预报的基础上，通过对气象卫星红外数字资料的定量处理和统计分析，作出降水云系的实时降雨量估计，并根据降水云系生命史的演变和移动、传播等特征，结合天气系统分型和雷达回波资料，提出一种北京密云水库上游潮河、白河流域区域性０—３小时强降水临近预报方法。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.
