琼北强天气触发机制的分析与预报着眼点的初步探讨

Preliminary probe into the key points for forecasting and analyzing the strong weather triggering mechanism in north Hainan

通过对 1989年 3～ 6月引发琼北强对流天气的机制分析 ,得出该地强对流天气的发生与锋面、切变线、SSW风与 SSE风的辐合线等中尺度天气系统有关 。

The analysis of the triggering mechanism of strong convection weather during March ~ June, 1989 in north Hainan showed that the occurrence of strong convection weather in north Hainan is related to the mesoscale synoptic systems, such as front, shearing line and the convergence line of SSW and SSE wind. In addition to this, the key points are put forward for forecasting strong weather under all kinds of mesoscale synoptic systems.
