A cylindrical column of air initially at rest at 43.3°N with radius 200 km contracts to half its original radius and moves to latitude 30°N. Derive an ex- pression for the final mean tangential velocity v in terms of the initial and final radii and the initial and final latitudes. Calculate the final mean tan- gential velocity at the perimeter after contraction? Is the motion cyclonic or anticyclonic?
