| 摘 要： | 通过对鲁西南一次区域性大暴雨的分析表明:除有利的大尺度环流背景以外,超低空急流是大暴雨不稳定能量和水汽的主要输送带,高能级、大面积的不稳定能量的积累和补充,有利的物理量场的配置,构成了这次大暴雨过程的维持和增强。暴雨落区与超低空急流前部最大风速切变区的位置对应较好。

| Abstract: | A regional rainstorm process were analyzed in southwest Shandong,the results indicated that super low-level jet is the main transportation belt of unstable energy and the water vapor besides the advantageous macro-scale circulation background.The high energy level and the big area unstable energy accumulation and the supplement, the advantageous physical varibles field disposition, constituted the maintenance and the enhancement of this rainstorm process and the fall area of rainstorm correspond with the location of maximum wind speed shear area front of super low-level jet is better. |

| Keywords: | regional rainstorm water vapor origin high-level and low-level jet |
