摘　　要：文章通过对2023年7月6—7日的泰州特大暴雨和6月18—19日暴雨过程进行对比分析,得到5840 gpm线的位置对暴雨落区有一定的指示意义,西南急流的强度和位置与暴雨量级和落区有较好的相关性,K指数在梅雨期与对流的相关性较好,大气可降水量大于65 mm时对暴雨预报有一定指示意义。Through the comparative analysis of the extremely heavy rainstorm process in Taizhou on July 6 to 7,2023,and the rainstorm process on June 18 to 19,2023,it is found that the position of the 5840 gpm line has a certain indication significance for the rainstorm falling area,the intensity and position of the southwest jet have a good correlation with the magnitude and falling area of the rainstorm,the K index has a good correlation with convection in the Meiyu period,and the atmospheric precipitable water is greater than 65 mm has a certain indication significance for the rainstorm forecast.
