Dynamics problems for next time (uke 19): 7.36, 7.40.

HINT: 7.36: Think of the wave diagram which explains Rossby wave propagation (what happens to the relative vorticity when a parcel moves north). Now look at the barotropic PV equation. What happens when the parcel moves to shallower or deeper water?

HINT: 7.40: This involves the continuity equation. Work through 7.39 and then it will be clear how to do this.
