摘要
用自由大气实际风速取代地转风，得到了非定常均匀条件下阻力定律和边界层内参数的一些性质及相似性函数Ａ、Ｂ的特性。该方法和结果可应用于大气模式中的边界层参数化以及与相似性函数有关的一些研究。
The well known resistance law is suitable for stationary and homogeneous PBL.In this paper,the resistance law was extended to non stationary and inhomogeneous conditions by using the real wind in free atnosphere instead of geostrophic wind.The main characteristics of the internal parameters of the PBL and similarity functions are thus obtained in non stationary and inhomogeneous conditions.The methods and results of this paper can be applied in the PBL parameterization of atmospheric models and some problems concerning in similarity functions.
