| 摘 要： | 对2014年7月18-19日桂东南受1409号台风＂威马逊＂影响,出现一次降雨强度大、影响范围广、降雨时间长的暴雨过程进行水汽特征分析,得出和验证了有利于出现强降水的大尺度环流背景下,充分的水汽供应是暴雨形成的基本条件之一,水汽通量场反映了水汽源源不断向桂东南输送,水汽通量散度进一步反映有大量的水汽往桂东南输送。

| Abstract: | Based on the characteristic analysis of water vapor of a rainstorm in the southeast of Guangxi,which affected by the 1409 typhoon ＂ Rammasun＂ on July 18 to 19,2014,the result shows that adequate water supply is one of the basic conditions for the formation of rainstorm under the large scale circulation background,appearing strong precipitation.The water vapor flux field reflects the continuous vapor transportation to the southeast,and the water vapor flux divergence reflects plenty vapor transportation to the southeast. |
