Summary:Simulation of planetary wave breaking and polar vortex erosion in the stratosphere has been carried out using three different global shallow water numerical models. The models are an Eulerian spectral model, a semi-Lagrangian finite difference model based on a vector discretization of the momentum equation and a semi-Lagrangian finite difference model based on the potential vorticity and divergence equations. The results of the integrations indicate advantages of the potential vorticity-based model in the vortex erosion problem.
