A wind stress of 0.2 N m-2 blows over an initially stationary freshwater lake, 20 km long, and moves water downwind in the upper 10 m of the 20 m deep lake. (a) Estimate the difference in lake level between the ends of the lake in the direction of the wind one would expect when the wind force is balanced by the opposing pressure force in the upper 10 m (assuming no Coriolis influence in the dynamical balance) (b) The current driven in the lower 10 m by the pressure force which is balanced by the vertical frictional forces characterized by a coefficient of vertical turbulent eddy viscosity Az=0.02 m2 s -1 .
