The following vertical sections show the sea level, layer thickness, temperature and vertical velocity fields in slices under the wind burst. The slices cut through the eddies as they are forming.
Note that sea level and mixed layer thickness are unrelated, similarly vertical velocity and mixed layer thickness. (Total model upper layer thickness (thick line) is (inversely) related to sea level since this is a reduced gravity model). The mixed layer returns to nearly flat almost immediately after the winds stop (day 6).
These features of the solution occur because the model mixed layer thickness is determined by Kraus-Turner physics. In this case, where the forcing is solely wind (no buoyancy), mixed layer thickness changes (dh/dt) are due entirely to stirring. Vertical velocity, which is due to horizontal divergence within the mixed layer, does not affect the interface depth.
Opposite to the observations and the MLE model, this model shows the anti-cyclonic eddy decaying and disappearing, while the cyclonic eddy remains and propagates west! The propagation speed is about 7 cm/s.
