Generalized Eady Waves with Ekman Pumping
GARETH P. WILLIAMS, John B. Robinson · Journal of the Atmospheric Sciences · 1974
The effects of Ekman layers on generalized Eady waves (i.e., height-varying static stability and shear) are examined. The non-constancy of N(z) and uz modify the classical Eady results but do not introduce any new effects. Thus, a short-wave cutoff is always found for flows with double Ekman layers but never for flows with a single Ekman layer. By comparing the analytical solutions with a numerically simulated annulus wave, we are able to categorize the latter quite accurately.
