Why does relative vorticity in spherical coordinates have an extra term as compared to the usual cartesian derivation?

The best way to see this extra term is to consider a bug moving along a latitude circle at constant speed $|u|$ in a constant direction arounf the poles. If the bug is moving along a geodesic then ...

Why is the zonal component of flow in the ocean much larger than the meridional component

It is more of a consistency argument: if a constant-depth ocean with much less relative vorticity than planetary vorticity is to stay that way, the flow must be zonal. If there were significant ...
