An extensive literature is devoted to the study of the boundary layer of the atmosphere over an inhomogeneous underlying surface. However, the specificity of anisotropic boundary layers, when the effective roughness and drag coefficient depend on the wind direction, has been studied to a much lesser extent. Such situations, in addition to cases of anisotropic relief, exist, for example, when the wind interacts with ordered vegetation (forest plantations) or ordered buildings. There are known facts of anisotropy of resistance over a rough sea surface. In this note, we consider a stationary nonlinear analytical model of the Ekman-type boundary layer with anisotropic resistance. The results show that the effects of anisotropy can be noticeable.
