Abstract: A shooting method is applied to a 100-level perturbation model with an explicit Ekman layer. Growth rates for a no-slip boundary condition are similar to those found previously. It is noted that the large cross-isobaric flow of the classic Ekman solution overestimates the damping by roughly a factor of 2. For the condition of zero vertical gradient of perturbation streamfunction at the lower boundary (allowing slip), growth rates are only slightly reduced from the frictionless case. The physical bases for an implicit boundary layer, as well as the no-slip condition, are questioned.
