This indicates that the horizontal mean and dynamic pressiire gradients are 

 balanced by the vertical gradient of the Reynolds stresses. 



In general, the mean horizontal pressure gradients in this simple model 

 can only be a resoolt of vi.nd set-up along a coast or in a bay. The important 

 thing is that the depth variation of the observed Reynolds stress is not neces^ 

 sarily controlled only by the eddy diffusion properties of the waves ^but by 

 fundamental dynamic conditions associated with the horizontal static and dynamic 

 pressure gradients,. More generally ;, the coriolis force must also be considered 

 as in the Eulerian theory-
