Large-Scale, Low-Frequency Barotropic Circulation on Continental Margins
Large-Scale Continental Margins Low-Frequency Barotropic Circulation
2008/12/27
Analytic solutions are obtained for forced, barotropic circulation at subinertial frequencies over a bilinear continental margin (shelf and slope) in situations where bottom friction is important. Thr...
Large-Scale SST Variability in the Western North Atlantic Subtropical Convergence Zone during FASINEX. Part II：Upper Ocean Heat Balance and Frontogenesis
subtropical frontal zone sea surface temperature Upper Ocean Heat Balance Frontogenesis
2008/12/27
We analyzed the influence of wind-deriven horizontal heat advection on the large-scale [O(1000) km wavelength] variability of both the upper-ocean mixed-layer heat content and the subtropical frontal ...
Large-Scale SST Variability in the Western North Atlantic Subtropical Convergence Zone during FASINEX. Part I：Description of SST and Wind Stress Fields
Wind Stress Fields Large-Scale SST NOAA ATOLL Subtropical Convergence Zone
2008/12/27
We describe properties of large-scale fluctuations in the wind field represented by two analyses (FNOC and NOAA ATOLL), and in the SST field represented by maps derived from 5-day composite AVHRR imag...
On the Catalytic Role of High Baroclinic Modes in Eddy-driven Large-Scale Circulations
Catalytic Role High Baroclinic Modes Eddy-driven Large-Scale Circulations
2008/12/24
This paper investigates the tridimensional consistency of the resolution of eddy scales in simulating large-scale flows. The generation of classical wind-forced, eddy-driven double-gyre circulation is...
Representing Topographic Stress for Large-Scale Ocean Models
seafloor topography Large-Scale Ocean Models ocean circulation
2008/12/22
Interaction of eddies with seafloor topography can exert enormous, systematic forces on the ocean circulation. This interaction has been considered previously under idealized circumstances. Theoretica...
Determining the Mean, Large-Scale Circulation of the Atlantic with the Adjoint Method
Large-Scale Circulation Atlantic Adjoint Method
2008/12/19
A new model approach based on the adjoint formalism and aimed at assimilating large sets of hydrographic data is presented. The goal of the model calculations is to obtain the mean, large-scale ocean ...
Sensitivity of a Large-Scale Ocean Model to a Parameterization of Topographic Stress
Large-Scale Ocean Model Topographic Stress
2008/12/17
A conventional ocean model was revised to include a tendency for velocities to relax toward a maximum entropy solution that depends on the shape of topography. The tendency, called topographic stress,...
Diapycnal Mixing in the Ocean：Equations for Large-Scale Budgets
Diapycnal Mixing Large-Scale Budgets Osborn–Cox model
2008/12/15
The Osborn–Cox model is the basis for the most direct estimates of the diapycnal diffusivity Kv for tracers. When used to interpret temperature variance dissipation measurements, it leads to Kv of O (...
Effects of Bottom Topography in the Large-Scale Circulation of the Southern Ocean
Bottom Topography Southern Ocean Large-Scale Circulation
2008/12/12
The characteristics of an unforced, stratified f-plane geostrophic flow over topography are described, and scaling arguments are made to justify the use of such a flow as a first-order approximation t...
Influence of Topography on the Large-Scale Ocean Circulation

2008/12/12
The influence of the bottom topography on the large-scale ocean circulation is discussed and illustrated with a simple model based on the ideal-fluid thermocline equations. The requirement that fluid ...
