台风"卡努"在江苏产生暴雨的热力学诊断分析

作者研究了0515号台风“卡努”在江苏暴雨过程的影响。分析认为,主要由台风本身的气旋性涡旋所造成的区域性暴雨,位于其移向的右前方。通过物理量场诊断分析发现,暴雨的落区,基本上位于底层的非绝热冷却区,非绝热冷却中心的走向,预示未来6h降水的落区。台风向前方的非绝热增温的方向移动,并有加速的趋势。

Diagnostic analysis with thermodynamic of landing typhoon Khanun in JIANGSU heavy rain course

The heavy rain gives rise in Jiangsu,when the typhoon of 0515 is around landing.Chiefly there is created by its cyclonic vortex itself.It locates at the right-front side of its movement direction.By diagnostical analysis by physical quantity it's found that the rain area locates at the diabatic cooling area on the lower layer.The direction of the center of the diabatic cooling area predict the area of the rainfall in 6 hour.The typhoon removs to the direction of the center of diabatic heating inside the strom and has the acceleration trend for the direction.
