WebbThe shallow water equations do not necessarily have to describe the flow of water. They can describe the behaviour of other fluids under certain situations. For example we can think of the atmosphere as a fluid. The equations governing its behaviour are the Navier-Stokes equations; however, these are notoriously difficult to solve. Webbsimplified version of the quasi-geostrophic potential vorticity equation for the upper ocean layer results in a differential equation for the averaged relative vorticity in which the mean divergence of the eddy vorticity fluxes acts as a source or sink. The essential part is that these eddy fluxes can be determined from the altimeter observations. WebbIf we eliminate all of the terms in the equation that have anything to do with temperature changes, either produced sensibly or by advection, the equation is considerably simplified. The resulting equation is called the … toyota prado fixed price servicing
