Abstract:

Motivated by the observed anti-correlation between Greenland and Antarctic temperatures, ocean mechanisms are investigated by which Southern Ocean winds influence North Atlantic circulation. The original Toggweiler and Samuels experiments are revisited to account for the effects of, firstly, an energy based representation of diapycnal mixing; secondly, resolved mesoscale eddies; and lastly, resolved coastally trapped waves. Comparisons with current non-eddy-resolving models then highlight where current eddy parameterizations fall short and where simulated remote connections should not be trusted.
