| 摘 要： | 利用常规观测资料对2006年5月27日广西一次强降雨过程进行分析。结果表明,这次强降雨发生在高空槽、切变线和地面冷锋共同配合的天气系统中,副热带经圈环流上升支和极锋急流经圈环流对暴雨区的生成具有重要作用。边界层南风急流、低空西风急流和高空西风急流上下的耦合作用是暴雨发生的重要原因。

| Abstract: | Based on conventional observation data,a process of heavy rainfall on May 27th,2006 in Guangxi was analyzed. It was found that the heavy rainfall occurred in the weather system that the upper trough and shear work with surface cold front. The sub-tropical meridional circulation ascending branch and the meridional circulation of polar front jet stream play important role for the storm area formation. The coupling interaction between boundary southerly jet,low-level westerly jet and upper-level jet was the important reason for heavy rain. |
