珠江三角洲地区一次强对流天气物理量场的分析

Diagnostic Analysis on Physical Variant Fields of One Strongly Convective Weather Process over the Delta of Pearl River

本文对珠江三角洲地区1983年9月24日在副热带高压控制下强对流天气发生的物理量场进行分析，发现这次强对流天气是在有利的环境条件下发生的。指出了这次强对流天气的可能触发条件，对今后预报此类强对流天气有重要意义.

In this paper, the physical variant fields of a strongly convective weather process ocurred on 24 September 1983 over the Delta of Pearl River are analysed. It has been found that this strongly convective weather process did occur under some singular enviromental conditions. The possible trigger mechanisms for the convective process have been discussed,which will provide some important criteria for the forecast of strongly convective weather processes.
