Stokes Transport by Gravity Waves for Application to Circulation Models
Stokes Transport Circulation Models Gravity Waves
2009/3/24
Stokes mass transport by surface gravity waves is related to the often more interesting Lagrangian transport in a manner that is complicated by the earth's rotation. This paper discusses the condition...
Surface Thermal Boundary Condition for Ocean Circulation Models
Surface Thermal Boundary Condition Ocean Circulation Models
2009/3/9
By employing a heat budget analysis appropriate to zonally and time averaged conditions within the atmosphere, it is shown that the net downward heat flux Q at the ocean's surface can be expressed as ...
The Stability of Ocean Currents in Eddy-Resolving General Circulation Models
Ocean Currents Eddy-Resolving General Circulation Models
2009/2/23
The stability of currents generated in an oceanic eddy-resolving general circulation model EGCM (Holland, 1978) is investigated by solving the eigenvalue problem associated with the finite-difference ...
Mixed Layers and Fronts in Simple Ocean Circulation Models
Mixed Layers Simple Ocean Circulation Models Fronts
2009/2/9
A three-dimensional regime with a differentially heated mixed layer on top of an ideal fluid interior is considered in a situation which corresponds to the interior of the well-known wind-driven model...
Current meter observations in Lake Ontario covering the 140-day period from 4 November 1982 to 23 March 1983 are used to evaluate the performance of circulation models for different time scales. The m...
Parameter Sensitivity of Primitive Equation Ocean General Circulation Models
Primitive Equation Ocean General Circulation Models Parameter Sensitivity
2009/1/7
Experiments with a low resolution, primitive equation ocean general circulation model with idealized basin geometry and surface forcing have been carried out in order to identify the processes control...

2008/12/18
A hierarchy of coarse-resolution World Ocean experiments were integrated with a view to determining the most appropriate representation of the global-scale water masses in ocean general circulation mo...
Thermohaline Oscillations Induced by Strong Steady Salinity Forcing of Ocean General Circulation Models
Thermohaline Oscillations Ocean General Circulation Models
2008/12/18
A series of numerical experiments is conducted with a three-dimensional ocean general circulation model and a two-dimensional counterpart both designed for efficient integration over diffusive (millen...
The Vertical Advection of Momentum in Bryan-Cox-Semtner Ocean General Circulation Models
Vertical Advection Bryan-Cox-Semtner
2008/12/12
This paper is concerned with the way that the Bryan-Cox-Semtner type ocean general circulation models represent the vertical advection of momentum, particularly at horizontal scales which are only sli...
Parameterizing Eddy-Induced Tracer Transports in Ocean Circulation Models
Eddy-Induced Tracer Transports Ocean Circulation Models
2008/12/11
It is shown that the effects of mesoscale eddies on tracer transports can be parameterized in a large-scale model by additional advection and diffusion of tracers. Thus, tracers are advected by the ef...
The Role of Horizontal Boundaries in Parameter Sensitivity and Decadal-Scale Variability of Coarse-Resolution Ocean General Circulation Models
Horizontal Boundaries Parameter Sensitivity Coarse-Resolution Ocean General Circulation Models
2008/12/8
Coarse-resolution f-plane and β-plane frictional geostrophic models are used to study the response to restored surface buoyancies and fixed surface buoyancy fluxes. With restored surface buoyancies it...
Abyssal Channel Flow in Ocean General Circulation Models with Application to the Vema Channel

2008/12/3
An idealized Cox model is shown to pass a flux given by g′H2/2f though a deep channel, single grid-box wide, consistent with analytical models. This flux can, however, be significantly increased or de...
