Dynamic Enthalpy, Conservative Temperature, and the Seawater Boussinesq Approximation
Publisher: American Meteorological Society
Abstract: A new seawater Boussinesq system is introduced, and it is shown that this approximation to the equations of motion of a compressible binary solution has an energy conservation law that is a consistent approximation to the ...
An Exact Thickness-Weighted Average Formulation of the Boussinesq Equations
Publisher: American Meteorological Society
Abstract: he author shows that a systematic application of thickness-weighted averaging to the Boussinesq equations of motion results in averaged equations of motion written entirely in terms of the thickness-weighted velocity; that ...
Two-Layer Baroclinic Eddy Heat Fluxes: Zonal Flows and Energy Balance
Publisher: American Meteorological Society
Abstract: The eddy heat flux generated by statistically equilibrated baroclinic turbulence supported on a uniform, horizontal temperature gradient is examined using a two-layer ?-plane quasigeostrophic model. The dependence of the ...
Scaling Baroclinic Eddy Fluxes: Vortices and Energy Balance
Publisher: American Meteorological Society
Abstract: The eddy heat flux generated by the statistically equilibrated baroclinic instability of a uniform, horizontal temperature gradient is studied using a two-mode f-plane quasigeostrophic model. An overview of the dependence ...
On Galerkin Approximations of the Surface Active Quasigeostrophic Equations
Publisher: American Meteorological Society
Abstract: his study investigates the representation of solutions of the three-dimensional quasigeostrophic (QG) equations using Galerkin series with standard vertical modes, with particular attention to the incorporation of active ...
Numerical and Analytical Estimates of M2 Tidal Conversion at Steep Oceanic Ridges
Publisher: American Meteorological Society
Abstract: Numerical calculations of the rate at which energy is converted from the external to internal tides at steep oceanic ridges are compared with estimates from analytic theories. The numerical calculations are performed using ...
Refraction and Straining of Near-Inertial Waves by Barotropic Eddies
Publisher: American Meteorological Society
Abstract: Fast-moving synoptic-scale atmospheric disturbances produce large-scale near-inertial waves in the ocean mixed layer. In this paper, we analyze the distortion of such waves by smaller-scale barotropic eddies, with a focus ...
Interaction of Near-Inertial Waves with an Anticyclonic Vortex
