This example demonstrates the dynamical meaning of the Rossby radius of deformation. As shown in Eqns. (4.474) and (4.475), free surface perturbations in the final state are confined within the order of the Rossby radius of deformation.
The discussion in the previous section is limited to a one-dimensional model with two fronts. In this section, we discuss the temporal evolution of barotropic adjustment in a two-dimensional f-plane.
