geostrophic vorticity

If pressure is taken as the vertical coordinate and the variability of the Coriolis parameter is neglected, the geostrophic relative vorticity ζg is given by
where g is the acceleration of gravity, f the Coriolis parameter, z the height of the constant- pressure surface, and ∇p2 is the isobaric Laplacian operator.
