摘要
利用ncep再分析资料,对1990～2003年期间,广西14次热带气旋特大暴雨过程进行850hPa低空急流的合成分析,结果指出:广西热带气旋特大暴雨的产生伴随着中南半岛西南急流的增强,西南急流是暴雨增幅的主要水汽和能量输送系统。另外,结合大尺度环流系统的分析给出广西热带气旋特大暴雨的概念模式。
There were forteen typhoon(including tropical depression) torrential rain events in Guangxi province during period from 1990 to 2003. By analyzing resultant of the LLJ on 850 hPa of different class base on ncep/ncar reanalysis data. It is found that the southwesterly LLJ from southern South-China Sea and Bengal gulf enhanced when typhoon torrential rain occurred .The LLJ was the main systems causing rain enhanced and provided abundant moisture and energy.In addition,an conceptual model of Typhoon Torrential Rain in Guangxi is constructed in connection with large scale circulation system analysis.
