caption: A dynamical recipe for the world's largest ocean current winds and buoyancy forcing drive a current around Antarctica density surfaces tilt up to the south, in balance with current eventually the current goes unstable, spawning eddies eddies transfer momentum downward, and heat and mass poleward (so east-west and north-south flows are coupled) vertical transfer of momentum sets up deep currents interaction of deep currents with bathymetry establishes stresses on the sea floor to balance momentum and vorticity budgets.
