摘　　要：此次过程主要由500 hPa短波槽和700 hPa切变线共同影响造成,经订正后的CAPE值较大,伴随前期高温晴热天气,具备能量、动力、水汽条件,0℃层和-20℃层高度适宜冰雹的发展。从风暴发展的强度ZH、速度V、双偏振参量ZDR、KDP、CC分析了强风暴发展过程的水平和垂直参数。This process is mainly caused by the combined influence of 500 hPa shortwave trough and 700 hPa shear line.After correction,the CAPE value is relatively high,accompanied by high temperature and sunny weather in the early stage,with energy,power,and water vapor conditions.The 0℃and-20℃layers are suitable for the development of hail.The horizontal and vertical parameters of the development process of strong storms were analyzed from the intensity ZH,velocity v,polarization parameters ZDR,KDP,and R2 of storm development.
