Abstract：The article analyzes the severe convective weather process on May 9,2022 by using data such as the Guizhou provincial artificial precipitation enhancement operation decision analysis system(CPAS),MICAPS sounding data,the integrated shortterm forecast and early warning platform of Guizhou Meteorological Bureau and the forecast products of CPEFS model.The results show that the banded echo is generated under the influence of low vortex shear and surface convergence line,causing severe convective weather processes such as thunderstorms,hail,strong winds and shortterm heavy precipitation in the areas west of central Guizhou.At the time of hailfall,the intensity of the echo center is as high as 60 dBZ,and the height of 45 dBZ is more than 9 km,all above 0 ℃.In this process,early warning is given in advance and upstream and downstream joint defense is implemented.The Qianxinan Prefecture timely carries out hail suppression work,and the operation achieves an effective hail suppression effect.
