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.

? p and ? surfaces are parallel

Barotropic flow:. ? p and ? surfaces are parallel. For a barotropic flow, we have. is geostrophic current. Since. ?. Given a barotropic and hydrostatic conditions,. and. Therefore,. By definition, ? ? and ? t are both constant in barotropic flow. And. So.
