On the Generation of Geostrophic Eddies by Surface Buoyancy Flux Anomalies
Geostrophic Eddies Surface Buoyancy Flux Anomalies
2009/2/13
Stochastic fluctuations in the buoyancy flux at the air-sea interface create density anomalies in the oceanic surface layer, which drive quasi-geostrophic motions in the ocean interior. The efficiency...
On the Effects of Buoyancy Flux on Continental Shelf Circulation
Buoyancy Flux Continental Shelf Circulation
2009/2/13
The effects of surface buoyancy flux. atmospheric wind stress and bottom topography on the horizontal and vertical structure of the density and alongshore velocity fields over a continental shelf are ...
Gyres Driven by Combined Wind and Buoyancy Flux
buoyancy forcing interfacial flux gyre-scale ocean circulation
2009/1/13
The combined effects of buoyancy forcing and wind in a gyre-scale steady ocean circulation are modeled using discrete layers with an interfacial flux, not necessarily vertical. The equations for vorti...
The Influence of Buoyancy Flux from Estuaries on Continental Shelf Circulation
Buoyancy Flux Estuaries Continental Shelf Circulation
2009/1/9
The release of freshwater from a midlatitude estuary to the continental shelf is modeled numerically as a Rossby adjustment problem using a primitive equation model. As the initial salinity front is r...
A Buoyancy Flux-Driven Cyclonic Gyre in the Labrador Sea
geostrophic equilibrium Buoyancy Flux-Driven Cyclonic Gyre Labrador Sea
2009/1/6
The generation mechanism for a wintertime cyclonic gyre in the western Labrador Sea, first observed by Clarke and Gascard, is studied by using simple theoretical models. It is shown that atmospheric c...
Maximizing Buoyancy Flux across Layered Geostrophic Sections
Maximizing Buoyancy Flux Layered Geostrophic Sections ocean stratification
2008/12/27
For layered analogues of the ocean stratification, the problem of maximizing buoyancy flux across a section with zero mass flux is considered. The two layer situation on an f-plane is particularly sim...
A Numerical Study of a Shallow Sea Front Generated by Buoyancy Flux：Generation Mechanism
Shallow Sea Front Buoyancy Flux Generation Mechanism
2008/12/27
We studied numerically the frontogenesis of shallow sea fronts such as are observed in the Kii Channel, Japan, during winter, under conditions of sea surface cooling and buoyancy influx from coast and...
Interdecadal Variability in an Ocean Model Driven by a Small, Zonal Redistribution of the Surface Buoyancy Flux
thermohaline circulation sea surface temperature Surface Buoyancy Flux
2008/12/12
An idealized, three-dimensional model, of size comparable to the Atlantic, is used to study interdecadal variability of the thermohaline circulation (THC). In most of the model experiments, salinity i...
The Relationship between Water Mass Formation and the Surface Buoyancy Flux, with Application to Phillips’ Red Sea Model
Water Mass Formation Surface Buoyancy Flux Red Sea Model
2008/12/12
A buoyancy flux across the sea surface between the outcropping of isopycnals must be balanced by a subsurface diapycnal buoyancy flux. If this flux were only advective, its derivative with respect to ...
Deep-Water Properties and Surface Buoyancy Flux as Simulated by a Z-Coordinate Model Including Eddy-Induced Advection
Deep-Water Properties Z-Coordinate Model Surface Buoyancy Flux Eddy-Induced Advection
2008/12/10
A parameterization for the adiabatic transport effect of eddies is introduced into a World Ocean model based on the Bryan-Cox code. The model topography is only lightly smoothed and retains realistic ...
An Apparent Surface Buoyancy Flux Associated with the Nonlinearity of the Equation of State
annual-average surface buoyancy flux Nonlinearity
2008/11/12
The temperature dependence of the expansion coefficient of seawater can lead to a nonzero annual-average surface buoyancy flux even if the annual-average heat flux is zero. In the Mediterranean Sea, f...
Deep water formation at high latitudes is believed to be the driving mechanism behind the ocean's thermohaline circulation. The exchange of heat and water with the atmosphere causes the density of the...
