Quasi-Geostrophic 3-Dimensional E-P Flux of Stationary Waves on a Sphere

Abstract

We formulate the quasi-geostrophic 3-dimensional E-P flux of stationary waves by means of a quasi-geostrophic potential vorticity equation on a sphere with a divergent component introduced by Matsuno (1970, 1971). It is found that the expression for the E-P flux has the same form as that of Plumb (1985), even when the wave is represented by a geostrophic wind with a divergent component.
