THE ROLE OF MESOSCALE TRACER TRANSPORTS IN THE GLOBAL OCEAN CIRCULATION

Ocean models routinely used in simulations of the Earth's climate do n ot resolve mesoscale eddies because of the immense computational cost. A new parameterization of the effects of these eddies has been implem ented in a widely used model. A comparison of its solution with that o f the conventional parameterization shows significant improvements in the global temperature distribution, the poleward and surface heat flu xes, and the locations of deepwater formation.
