Abstract 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.
