Geostrophic adjustment

Geostrophic adjustment. Question: How does the adjustment to geostrophy take place?. H(1 + h o ). H(1 - h o ). 0. x. u-momentum. (1). v-momentum. (2). continuity. (3). Take the divergence of (1) and (2) and use (3) to eliminate the divergence. The nonrotating case ( f = 0 ).

The Quasi-Geostrophic Omega Equation (without friction and diabatic terms)

THE TRENBERTH (1978) INTERPRETATION. The Quasi-Geostrophic Omega Equation (without friction and diabatic terms). PROBLEM: TERM 1 and 2 on the RHS are often large and opposite leading to ambiguity about the sign and magnitude of ? when analyzing weather maps.
