云南强冷空气过程的特点

The Features of the Processes of Strong Cold Air in Yunnan

本文对影响云南各地的强冷空气过程进行了统计分析。发现云南大部分地区强降温过程次数明显少于我国东部地区,但过程降温日数较多。在云南存在锋面附近的雨雪天气和造成重霜冻的晴好天气两种寒潮天气过程。

In this paper the processes of strong cold air affecting the various regions in Yunnan province have been analyzed statistically. We found that the times of the processes of strong decrease in temperature in most part in Yunnan are lesser than that in east part of China obviously and the days of the processes are more. Meantime there are two kinds of weather of the cold wave, one of them is expressed as rainy or snowy day near the front, another is successive clear days result in severe frost hazard.
