摘　　要：应用常规气象资料和mieaps资料，对2007年7月7～9日泰州地区梅雨期内连续暴雨天气进行分析。结果表明：这次连续暴雨是典型的梅雨期暴雨，高空急流、中低层切变线、地面静止锋是产生这次暴雨的重要系统。通过对对流有效位能（cAPE）的分析表明，暴雨落区基本在有效位能（CAPF）t〉750J／k区域，对暴雨落区的预报有较好的指导意义。同时，对高低空急流、K指数、垂直速度、水汽通量、总温度场、涡度场等物理量进行了初步的诊断分析。Applying conventional meteorological data and micaps material to analyze a continual rainstorm process in Taizhou area during July 7 - 9,2007 during the plum rains time, the restdts indicated that this continual rainstorm was the typical plum rains time rainstorm and formed by the system of upper air jet stream,underlyiing bed shear line and ground stationary front. An analysis to the convection effective potential energy CAPE indicated the rainstorm fallen within the area of the effective potential energy CAPE ≥ 750 J/kg,these results were meaningful in the forecast of the rainstorm.At the same time this study carried on the preliminary diagnostic analysis to high or low altitude jet stream, K index, vertical velocity, water vapor flux, total temprature field,field of vorticity and other physical quantities.
