漳州市一次强冰雹天气过程分析

Analysis on a heavy hail weather process in Zhangzhou

文章利用NCEP全球再分析资料和常规观测资料对2016-03-19漳州市的一次强冰雹天气过程进行分析,得出此次冰雹过程是在有利大尺度环流背景下的一次中尺度对流天气过程。当径向速度出现中气旋特征、垂直累积液态水含量出现跃增现象时,预示着即将出现冰雹天气。研究成果对冰雹的短时预报有着较好的指示意义,可更好地提供冰雹的预警预报服务。

Based on the NCEP global reanalysis data and conventional observation data,this paper analyzes a heavy hail weather process on March 19,2016 in Zhangzhou.It is concluded that the hail process is a mesoscale convective weather process under the background of favorable large-scale circulation.When the radial velocity shows the characteristics of mesocyclone and the vertical cumulative liquid water content shows a jump phenomenon,it indicates that hail weather is about to occur.The research results have a good indicative significance for the short-term forecast of hail,and can better provide the early warning and forecasting service of hail.
