| 摘 要： | 运用常规气象资料和卫星云图，分析了１９９６年８月３—５日河北特大暴雨的成因。认为：它是出现在东亚特定的强经向环流形势下，由９６０８号台风低压与副热带高压两侧之间形成的强偏南风低空急流，将低纬度地区高温高湿水汽源源不断地向华北输送并与近地面层弱冷空气相互作用，诱发两个中尺度云团的形成和发展直接造成的

| Abstract: | The reason of the extreme rainfall event occurred in 3-5 August 1996 over Hebei province has been studied using conventional meteorological data and satellite imagery.The results show that the event presented itself in a strong meridional circulation in eastern Asia and stronger low level southern jet which was caused by stronger pressure gradient between typhoon low and subtropical high.The jet transmitted high thermal and moisture air from the tropics to North China,and interacted with weaker cold air near surface.And generated and developed were two mesoscale cloud clusters causing the extreme rainfall directly. |
