WebQUASI-GEOSTROPHIC HEIGHT TENDENCY EQUATION The quasi-geostrophic vorticity, thermodynamic, and mass continuity equations can be combined to determine where … Web3. Quasi-geostrophic (QG) theory In quasi-geostrophic (QG) theory only the vertical component of the vorticity equation (equation (A8)) is explicitly considered. It is also supposed that the Earth’s rotation dominates: ζ≅f. The relevant vorticity equa-tion (equation (A15)) then contains only stretching and shrinking of this basic rotation.
