Asymptotic expressions for the wind components u, v obtained via the WKB method retain the form and, to a large extent, the simplicity of the classical case in which K is kept constant. Three examples of idealized K-profiles are used to compare the numerical, WKB and constant-K solutions for Ekman profiles.
