| 摘 要： | 应用MICAPS常规资料结合FY-2卫星云图,通过天气分析与物理量诊断分析方法,对红河州2007年5月16～18日的持续性强降水天气过程进行了分析。这次过程主要影响天气系统为初夏孟加拉湾风暴、700 hPa切变线及地面冷锋,冷空气侵入孟加拉湾风暴外围环流导致强降水发展并持续。冷锋切变南下有利于水汽凝结量的增加及强降水天气发生发展环境的形成。孟加拉湾风暴带来的充沛水汽输送和强烈的上升运动与不稳定大气为持续强降水发生发展提供了有利条件。卫星云图上强对流云团覆盖区与红河州强降水区相对应。

| Abstract: | By using the conventional MICAPS materials,FY-2 Satellite Cloud Maps,weather analysis and the physical diagnosis,this article analyzes the continuous strong rainfall weather occurred in Honghe Prefecture during 16th-18th May 2007.This strong continuous rainfall weather was mainly affected by three factors: the weather system from Bengal Bay storm,700 hPa shear line,the surface cold-front.The encroachment of cold air and the strong rainfall caused by the spiraling circulation of the Bengal Bay storm,which ma... |
