摘要
对贵阳机场2010年2月27日一次低云天气过程进行各物理量的诊断分析.结果表明:昆明静止锋是造成此次低云的主要影响系统;充沛的水汽、冷却过程和弱上升运动是此次低云形成必要条件;此次低云的形成伴随着低层弱冷温度平流的出现.因此通过诊断分析所得到的低云发生环境和气象要素条件,可对预报贵阳机场低云的发生有一定的参考价值.
The article analyze some physical factors of the low clouds weather on Feb 27,2010 in Guiyang airport.The results show that the Yunnan and Guizhou stationary front cause the low clouds weather.The plenty of vapour,cooling procedure and weaken ascending motion are the main condition to cause the low clouds weather.and accompanying with the weaken temperature advection of low level.So the environment and weather condition of low cloud by diagnosis analysis will afford some method to forecast low cloud weather in Guiyang airport.
