摘　　要：2006年7月14日—8月11日,“碧利斯”、“格美”、“桑美”3个台风先后进入江西,均产生了较强的区域性暴雨或大暴雨。利用常规资料和T213资料,对这3个台风的移动路径和暴雨形成机制进行了对比分析。分析结果表明,台风登陆后,由于副高形态和演变的不同,使得各台风路径变化不同。由于“碧利斯”登陆后与强西南季风结合,造成“碧利斯”暴雨的水汽、动力、热力条件均强于“格美”和“桑美”,从而使“碧利斯”暴雨的强度和范围明显强于“格美”和“桑美”。From July 14th to August llth in 2006, there were three typhoons named BILIS, KAEMEI and SAOMEI hitting China and all of them brought regional heavy rainfall. Based on the data of daily observation and T213, we compared the three typhoons on the routes and the mechanisms of heavy rainfall. The results show that the different configuration of the Northwest Pacific Subtropical high caused the different routes of the three typhoons and the interaction of BILIS and the South China Sea summer monsoon made BILIS produce heavier rainfall and impact more extensive areas than KAEMEI and SAOMEI.
