摘要：
We study the geophysical fluid dynamics problem in the steady atmospheric Ekman layer for height-dependent eddy viscosities in the form of some quadratic and rational power functions. We use the appropriate boundary conditions to obtain the wind velocity profiles analytically. For these Ekman-type solutions, the angle between the wind vector at the bottom and the geostrophic wind vector can be smaller or bigger than the traditional value of <mml:mfrac>pi 4</mml:mfrac>.
