Description:
A new high-resolution Eulerian numerical method is proposed for modelling quasigeostrophic ocean
dynamics in eddying regimes. The method is based on a novel, second-order non-dissipative and lowdispersive
conservative advection scheme called CABARET. The properties of the new method are
compared with those of several high-resolution Eulerian methods for linear advection and gas
dynamics. Then, the CABARET method is applied to the classical model of the double-gyre ocean
circulation and its performance is contrasted against that of the common vorticity-preserving Arakawa
method. In turbulent regimes, the new method permits credible numerical simulations on much coarser
computational grids.
