Vortex Simulations

This page contains some simple two dimensional simulations of vortex motion produced by the Contour-Advective Semi-Lagrangian (CASL) algorithm. For a detailed description of the CASL algorithm see: D. G. Dritschel and M. H. P. Ambaum. A contour-advective semi-lagrangian numerical algorithm for simulating fine-scale conservative fields. Q. J. R. Meteorol. Soc., 123:1097-1130, 1997. Click on each image to see the corresponding simulation.
