Parameterization of Eddy Fluxes near Oceanic Boundaries
In the stably stratified interior of the ocean, mesoscale eddies transport materials by quasiadiabatic isopycnal stirring. Resolving or parameterizing these effects is important for modeling the oceanic general circulation and climate. Near the bottom and near the surface, however, microscale boundary-layer turbulence overcomes the adiabatic, isopycnal constraints for the mesoscale transport. I...

Deep convection energizes the entire water column. Large-eddy simulation of the oceanic boundary layer system predicts turbulence in the well-mixed layer as well as turbulence-induced internal waves propagating into the underlying stratified water column of the freely convecting wintertime Labrador Sea. Of particular interest is the downward propagation of energy from the turbulent boundary lay...
متن کاملAssessing eddy heat flux and its parameterization: A wavenumber perspective from a 1/10° ocean simulation
Diffusivities diagnosed from eddy heat fluxes in eddying models tend to show unphysically large positive and negative values and it has been suggested that this is due to rotational components that do not influence the heat budget. We diagnose the rotational component of the horizontal eddy heat flux, as measured by its curl, in the Southern Ocean of the 1/10◦ Parallel Ocean Program as a functi...
متن کاملDispersive–Dissipative Eddy Parameterization in a Barotropic Model
Recently a new class of coarse-grained equations, known as a models, have been proposed for the mean motion of an ideal incompressible fluid. The use of one such model to represent the time-mean component of a turbulent b-plane circulation characterized by potential vorticity mixing is considered. In particular, the focus is on the wind-driven circulation in a shallow ocean basin, a problem wel...
