Buoyancy frequency

You can, but the form changes. it is $N^2=\frac{g}{T}(\frac{dT}{dz} + Γ)$ where $Γ$ is the dry adiabatic lapse rate, given by $g/c_p$ where $c_p$ is the specific heat of air at constant pressure.

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 ...
