This example shows the eastward propagation of two eddy structures in a finite difference barotropic ocean model. The numerical procedure uses adaptive mesh refinement with two levels of refinement. The coarse grid has a resolution of 25 km and covers the whole domain (1600 km x 1600 km). The fine grids have a resolution of about 6 km (refinement ratio = 4), and are located only where necessary, in order to achieve a given accuracy everywhere in the domain.
The rectangles on the plots indicate the locations of the fine grids (which mostly follow the eddy structures).
