2) A1V1 A2V2 Area 1 (A1) > Area 2 (A2), therefore Velocity 1 (V1) < Velocity 2 (V2) In between A1 and A2 the acceleration is no longer zero (not geostrophic) FLOW When the acceleration increases the coriolis acceleration increases because the coriolis accelertion is equal to twice the rotational constant multiplied by the velocity the flow is directed to the right
A1V1 A2V2 When Area increases the velocity decreases Where the area is changing the acceleration is no longer zero (geostatic) and becomes negative When acceleration decreases the Coriolis force decreases and the flow is directed to the left because of the pressure gradient

3) N V= 5m/s C P 1/2 mile 1.524 m/s 1.524 m/s .0122682 m
4) M, Ekman transport is the inverse relationship between wind stress (T) an the Coriolis parameter, f. The wind pushes on the top layer of water and that water is slightly deflected due to the Coriolis effect, each layer of water below is deflected slightly more.
