利用黔西南州8县市气象观测资料和近5 a micpas资料及NCEP再分析资料,对黔西南州雾的时空分布进行了分析,得出黔西南州雾与海拔高度的相关性较好;分析近5 a锋面雾的天气,得出形成黔西南州锋面雾的天气形势主要有南支槽前偏西气流型和高空槽后西北气流型;锋面雾发生时低层空气潮湿,整层大气层结较稳定,低层有逆温层存在,锋区附近有弱的上升运动。

By using meteorological observation data from eight weather stations in Southwest Guizhou and Micpas data and NCEP reanalysis data in recent five years,the spatial and temporal distribution of fog weather in Southwest Guizhou was analyzed in this paper.The results show that the main synoptic patterns resulted to fog weather here were the westerly flow in front of the southern trough and the northwest flow behind the upper trough,and physical quantity fields analysis indicated that the low-level air was wet when frontal fog appeared,and the atmosphere structure was relatively stable,there was a temperature inversion layer in lower level,and a weak upward motion nearby frontal area.
