摘要
本文分析了景洪市辐射雾的时空分布规律、生消机制、雾的微物理结构．结果表明：（１）景洪市辐射雾以雾季最多，１月份生成最早、消散最晚、持续时间最长；（２）离地表５０～１００ｍ为雾首先生成层，随后雾顶可抬至３００ｍ高处；（３）雾的生成主要因地面和大气的辐射冷却，而雾的衰退是因太阳辐射对地面的加热和热量向大气的湍流输送．
In this paper, the laws of temporal and spatial distribution, the physical mechanism of formation and dissipation,and the micrortructure of the radiation fog in Jinghong,Xishuangbanna are studied. The results show that 1) the radiation fog is the most in fog season, and in January it is formed the earliest and dissipated the latest, with the longest sustained time; 2) the fog is formed firstly at the layer between 50m tO 100m above ground level, then the top of the layer can rise to the height of 300m; 3) the formation of the fog is mainly caused by the radiative cooling of the earth surface and the atmosphere, and its dissipation is due to the heating of the ground by solar radiation and the turbulent tranSport of heat to the atmosphere.
