摘要: 本文系统地分析了任意分布的表面粗糙度变化,对三维和二维大气边界层近地风速和剪应力的影响,提出了一个四层结构的线性理论.由该理论得到的解与已有的结果符合得很好.

Abstract: A general four-layer structure linear theory for predicting the effects of arbitrarily distributed roughness change on the variations of wind speed and shear stress in the surface layer of 3D and 2D atmospheres was presented.The results derived by the theory were agreeable to the previous ones.
