| 摘 要： | 利用探空观测资料以及FY-2D气象卫星云图、多普勒天气雷达回波等非常规气象观测资料,采取天气学诊断分析方法,对2009年7月26日出现在广东清远市一次局地突发性暴雨过程进行了诊断分析。结果表明,副热带高压边缘的不稳定气流及南支槽前的上升运动是此次局地暴雨过程的天气尺度系统和大尺度环流背景;暴雨发生前大气不稳定能量不断积累,为中尺度系统形成创造了有利的环境条件;地形与降水有着密切的关系,中小尺度地形使近地面上升气流增强,造成了对流云团在该地不断生成和发展。

| Abstract: | In this paper,we use sounding observation data as well as the FY-2D weather satellite imagery,Doppler weather radar,and other unconventional data,and adopt synoptic diagnosis method to carry out a diagnostic analysis on a local rainstorm appeared in Qingyuan.The results show that:(1) In the course of this local rainstorm,the instable air flow of the subtropical high pressure edge and the air flow upward motion before southern trough are the synoptic scale systems and large-scale circulation background of th... |
