| 摘 要： | 利用NCEP/NCAR再分析资料,分析0814号强台风"黑格比"引发华南西南部严重暴雨洪涝特征及其成因.结果显示:①2008年9月下旬副高强度偏强,位置偏北偏西,台风易受其南侧偏东气流引导而西行;②台风"黑格比"强度强,辐合上升运动强烈,触发强降雨;③南海夏季风增强和季风辐合带北抬,西南暖湿气流强盛,增强了辐合上升运动,并为台风降雨带来了源源不断的水汽,使降雨加强和持续;④除了气象因素外,地形对西行台风降雨量的显著增幅作用,是造成强台风"黑格比"暴雨洪涝的重要原因.

| Abstract: | The strong typhoon "Hagupit"(No.0814)led to rainstorm and severe flood,and causes great damages in southwest part of South China.Based on the NCEP/NCAR data,the causality of the rainstorm and flood process are analyzed in this paper.The results show that:(1)During the late September in 2008,the western Pacific subtropical high(WPSH) was intensified,and extended westward and northward.The typhoons in the southern of the WPSH were easier to wove westward by the easterly guide-airflow.(2)Hagupit produced an up... |
