Vortensity

(PV, Potential Vorticity)
(ratio of vorticity to mass density)

Vortensity (physics) is the ratio of vorticity to mass density. It is known as the Potential Vorticity.

Vorticity is a measure of local angular rotation in a fluid flow, i.e., the curl of the flow's velocity field.

Vortensity comes into play in disk and disk/planet dynamics.
