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...
متن کاملOrientation of eddy fluxes in geostrophic turbulence.
Given its importance in parametrizing eddies, we consider the orientation of eddy flux of potential vorticity (PV) in geostrophic turbulence. We take two different points of view, a classical ensemble- or time-average point of view and a second scale decomposition point of view. A net alignment of the eddy flux of PV with the appropriate mean gradient or the large-scale gradient of PV is requir...
متن کاملEddy Correlation and Relaxed Eddy Accumulation measurements of CO2 fluxes over grassland
Abstract. Eddy correlation measurements of CO2 fluxes over grassland on peat soil were performed from April to October 1994. In this article the measurement system is described and some results are discussed. The closed path system was compared with an open path eddy correlation system developed at the Royal Netherlands Meteorological Institute (KNMI) in December 1994. Fluxes deduced from the r...
متن کاملEquilibration of an Atmosphere by Adiabatic Eddy Fluxes
A major question for climate studies is to quantify the role of turbulent eddy fluxes in maintaining the observed atmospheric mean state. Both the equator-to-pole temperature gradient and the static stability of the extratropical atmosphere are set by a balance between these eddy fluxes and the radiative forcing. Much attention has been paid to the adjustment of the isentropic slope, which rela...
