| 摘 要： | 应用常规气象资料通过诊断分析和湿Q矢量分析,探讨了2006年10月上旬云南严重连阴雨期间的水汽输送特征,进一步分析了期间持续性暴雨、大雨的落区分布,结果表明:连阴雨期间,ITCZ异常活跃,先后有4个热带气旋活动,200616号强台风"象神"横穿中南半岛进入孟加拉湾,减弱之后再度发展成孟加拉湾低压,由此提供了孟加拉湾水汽通道;ITCZ水汽通过副高外围气流向中南半岛输送,提供了第二条水汽通道,两条水汽通道呈"人"字形,为连阴雨发生发展提供了有利的水汽条件.湿Q矢量辐合中心在对流层中低层700～640 hPa之间,700 hPa上湿Q矢量散度辐合区与暴雨区对应较好;随着湿Q矢量辐合区加强、移动和减弱,暴雨随之发展、移动和结束.

| Abstract: | Observing data,diagnostic analysis and wet Q vector analysis are used to research on the water vapour transporting features during the severe lasting rainfall period of Yunnan Province in first third of October,2006.Furthermore,the distribution of precipitation area of lasting storm rainfall and heavy rainfall was analyzed.Result indicated that,during the lasting precipitation period,ITCZ was abnormally active,and there were 4 tropical cyclone activities one after another.The 200616 severe typhoon "Xiangshe... |
