Webow. This is the conservation of potential vorticity. The idea here is to formulate a scalar eld that is advected by the uid and which describes the evolution of uid elements. As we will see, potential vorticity is a consequence of the ‘frozen in’ property of vorticity. Below we examine potential vorticity in the case of both bartropic and ... Webpotential vorticity flux when the inhomogeneous bound-ary conditions for potential vorticity dynamics are re-placed by homogeneous boundary conditions. For the generalized potential vorticity, a conservation law holds that reduces, in the quasigeostrophic limit, to the con-servation law for Bretherton’s (1966) generalized qua-
