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1~2 h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。

Abstract: | Using conventional meteorological data and Doppler weather radar echo data,short rainstorm July 4,2014 occurred in Huzhou Deqing 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. |
