| 摘 要： | 分析了2008年08号台风“凤凰”的移动过程及其对江苏降水的影响。由其移动路径和移动过程中副热带高压的变化,以及影响江苏降水环流形势的演变可以发现,“凤凰”的移动路径主要受强大而稳定的副热带高压引导;西南季风和副热带高压南侧的东南风为台风降水输送了丰富的水汽,给江苏地区强降水提供了有利的环境场;冷空气的侵入也是台风“凤凰”登陆后造成江苏持续性降水的主要原因之一,但同时冷空气的入侵也破坏了台风的暖心结构,加快了台风的消亡。

| Abstract: | The track of ＂Fung-wong＂ typhoon （the 8^th typhoon in 2008） and its impact on precipitation are analyzed. The results show that the track was affected by the strong and stable subtropical high. The southwest monsoon and the southeast flow on the south of subtropical high supplied sufficient moisture for ＂Fung-wong＂, which provided favorable background of heavy rainfall in Jiangsu. The cold air intrusion is another essential factor for the continuous precipitation in Jiangsu. However, it also accelerated the decay of the typhoon by destructing its warm core. |
