摘要
本文主要研究大气能量场结构演变、数字化卫星云图相对亮度和云系特征与台风暴雨的关系,结论如下: 台风暴雨区的大气能量初始场为上层高能,下层低能,关键在于以后上下层能量是否能同时各自向相反方向转变及最后在铅直方向上将上下层高能区打通成能量通道.在数字化卫星云图上相对亮度大值区与台风暴雨区有很好的对应关系。将大气能量演变与数字化卫星云图配合起来预报台风暴雨,效果较好。
This paper mainly aims at studing the relation between the typhoon rainstorm and the areal structure of atmospheric energy and their changs with time in the ranges of typhoon and the relative brightness of the digitized satellite cloud picture, The results show that the heavy rainfall will occurr under the high energy tube and there is a close relationship between the high value area of the relative brightness of the digitized satellite cloud picture.
