Abstract
The classical analytical solution for the Ekman layer flow has been ge neralized by introducing an assigned non-rapidly-varying eddy diffusiv ity K(z). Asymptotic expressions for the wind components u, nu Q obtai ned via the WKB method retain the form and, to a large extent, the sim plicity of the classical case in which K is kept constant. Three examp les of idealized K-profiles are used to compare the numerical, WKB and constant-K solutions for Ekman profiles.
