DYNAMICS OF NON-LINEAR EKMAN BOUNDARY LAYER

The effects of non-linear advection on the wind structure and vertical motion in Ekman layer are studied.The effect of non-linear will reduce the vertical motion derived by Charney and Eliassen in the simple circular, stationary vortex. The effect also depends upon the characteristic feature of the pressure pattern. These results are discussed by comparing with that obtained under the assumption of the geostrophic momentum in this paper.
