We specify t, to take the same form as t in Problem 1. 

 The remaining shear stress terms are assumed to be negligible. 

 The boundary conditions are U-]_ = V-^ = U2 = Vp = on a land- 

 water boundary, i.e., vanishing mass transport in each layer. 

 These conditions are much more restrictive than the boundary 

 conditions of the one-layer problem since there can be no verti- 

 cal interchange of transport across the interface at the bound- 

 aries. 



Equations (25) - (30), together with the boundary condi- 

 tions and the wind-stress, constitute Problem 2, or the two-
