摘要
利用常规气象资料和多普勒天气雷达回波资料对2014年7月4日发生在湖州德清的短时暴雨天气过程进行了分析，结果显示：在大尺度天气背景下，辅以精细化的数值预报产品，降水云团的移动发展可通过外推预报技术进行预报，预报员可提前1～2h对此次短时暴雨过程作出预警，提高这类局地强对流天气临近预报的准确率。
Using conventional meteorological data and Doppler weather radar echo data,short rainstorm July 4,2014 occurred in Huzhnu l）eqing was analyzed. The results showed that in the large-scale weather background, combined with the refinement of the numerical forecast products, mobile development could be forecast precipitation clouds by extrapolation forecasting techniques.Forecasters could make short rainstorm warning for this process 1-2 h ahead of time,so as to improve accuracy for this kind of strong convective weather nowcasting.
