摘要: 摘要:[方法]利用常规天气图、数值预报产品和多普勒雷达资料,[目的]对2017年第10号台风“海棠”减弱后的热带低压进行综合分析,主要针对2017年8月2~3日其影响潍坊的一次强对流天气过程进行个例研究,[结果]结果表明:(1)此次强对流天气过程主要由台风减弱后的热带低压、冷空气和地面气旋共同影响造成的,系统动力抬升条件好,水汽输送条件好,再加上列车效应导致潍坊多个站点出现暴雨和大暴雨天气;[结论](2)几家数值预报产品对此次过程的天气系统预报差异较大,其中欧洲中心表现较好,对今后的预报有指导意义。

Abstract: Using synoptic chart, numerical forecast product and Doppler radar to analyze the weakened tropical depression of typhoon“Haitang”, the author studied the severe convective weather process in Weifang of August 2 to 3, 2017, which was caused by typhoon“Haitang”. The results showed that: (1) this severe convective weather process was mainly caused by the weakened tropical depression of typhoon, cold air and ground cyclone; the good dynamic lifting condition, nice vapor transport condition and train effect caused rainstorm and heavy rainstorm in many sites of Weifang; (2) the severe numerical forecast products had great difference in the prediction of this process, the European Central numerical model showed great performance and could guide future forecast.
