摘要
利用T213数值预报产品及有关常规天气资料,对2002年5月12~14日发生在中国西南地区的大范围暴雨天气过程进行了诊断分析。分析表明:此过程主要的影响系统是高空冷槽、地面冷锋以及高低空急流。暴雨落区位于具有强盛的垂直上升运动的高能、高湿舌的不稳定区内。
The heavy rainfall process during the period of 12~14 May 2002("02. 5") is diagnosed by the T213 output and conventional sounding data. The result shows that the event is caused by the upper trough, surface cold front and uppe r and lower-level jets. The heavy rainfall area locates in the instability regio n with strongly ascending motion, high energy and high humidity.
