Abstract
The dynamical control of the eddy-induced transport is investigated in a se ries of idealized eddy-resolving experiments. When there is an active eddy field, the eddy-induced transport is found to correlate with isopycnic grad ients of potential vorticity, rather than gradients of layer thickness. For any unforced layers, the eddy transfer reads to a homogenization of potent ial vorticity and a vanishing of the eddy-induced transport in the final st eady state.
