中文摘要: 对2001年8月19日发生在北京的暴雨通过诊断分析解释了其环流成因。结果表明,这是一次典型的由中纬度斜压系统引起的大尺度暴雨过程,它的发生机制可以用准地转运动理论得到很好的解释。
Abstract:The circulational cause of heavy rainfall of Beijing on 19 August,2001 is given through diagnostic analysis.The results show that it is a typical large scale heavy rainfall which is related to the middle latitude baroclinic disturbance.The mechanism of the heavy rainfall could be revealed by the qusai-geostrophic theory.This study is a complement to the heavy rainfall research which was concentrated on mesocale convective system nowadays.
