中文摘要: 计算了山东省不同天气系统、不同时间云中和晴空中的湍流扩散系数，主要结果为：云中3～4km高度层间的扩散系数主要在20～70m2·s－1间，晴空小于30m2·s－1；云中扩散系数的平均值一般随高度增加而增大，冬、夏半年各高度层上的K值相关不大。

Abstract:The turbulent diffusion coefficient is calculated with and without clouds in different weather systems at different time. The main results show that the turbulent coefficient of 3～4km height level distributes mainly between 20 and 70m2·s-1 in clouds,and less than 30m2·s-1 in cloud free areas. The turbulent coefficients in clouds generally increase with height,and little differences exist in every layer between winter and summer half years.
