08.03.11: Evolution of KE and APE in exp4, exp5 and exp6 (two-gyre case)

Fig. 1 shows the evolution of kinetic energy (KE) and available potential energy (APE) in exp4, exp5 and exp6. In all simulations, the domain is 40°by 40° , has 3 layers and the ocean is forced by a steady purely zonal wind stress with a sinusoidal meridional profile and a maximum amplitude of 1 dyn/cm2 in order to generate the classic double gyre. The forcing and stratification are the same as in Lozier and Riser (1989; 1990). The simulations vary in the number of points in the horizontal and the strength of Laplacian (KH) and biharmonic (AH) friction.
