Abstract:Using radar echo products,vertically integrated liquid water content,contour plane display,lightning distribution,thunderstorm clustering,lightning density,lightning frequency time series,and raindrop spectrum data from the Tianheng Tianyan system of the China Meteorological Administration,an analysis was conducted on a hail and strong wind weather process in Leping on April 2,2024.The results showed that the hail echo in Leping was ≥60 dBZ,and the vertically integrated liquid water content reached 70 kg/m2.When hail occurs,there are a large number of lightning strikes with a lightning density of about 0.5 lightning strikes per square kilometer.The Tianyan system predicts a high probability of hail,and from the vertical structure of hail clouds,the 60 dBZ strong echo extends up to a height of 7 km,which is a typical feature of hail.In terms of the structure of the raindrop spectrum,the maximum particle diameter in the convective cloud of Leping hail can reach over 100 mm,but the proportion of large particles is small and the velocity is slow.It is hoped that the research results can provide reference for monitoring and warning of hail and strong wind weather in Leping.
