摘　　要：本文利用常规观测资料、FY-2卫星云图资料、地面自动站观测资料,运用天气学诊断方法对2020年11月25日一次大雾天气发生机理进行分析研究。首先借助卫星云图从高低空影响系统、预报背景等方面分析雾的高低空形势特征,其次分别研究物理量变化与大雾生成发展的关系,最终得出此次大雾过程的物理机制。This paper uses Synoptic diagnostic methods,conventional observation data,FY-2 satellite cloud picture and ground automatic observation station data to study the mechanism of a heavy fog process on November 25,2020.First,using satellite cloud images to analyze the high-altitude and low-altitude situation characteristics of the fog from the aspects of high and low altitude influence system and forecast background.Second,the relationship between the change of physical quantity and the development of the fog is studied separately,and finally the physical mechanism of the fog process is obtained.
