(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 protoplanetary disk and disk/planet dynamics.
