Geostrophic vorticity

From Glossary of Meteorology



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
ams2001glos-Ge28
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.
