A Simple Topographic Model of Gulf Stream Separation
Simple Topographic Model Gulf Stream Separation
2009/3/7
A simple, frictional, linear model is used to study the motion of the Gull Stream over the continental shelf. It is found that the combination of frictional and topographic effects may provide a furth...
The Separation of Wave-Induced and Intrusive Oceanic Finestructure
Wave-Induced Intrusive Oceanic Finestructure
2009/2/23
Two hundred miles southwest of San Diego a conductivity/temperature/pressure instrument (CTD) was repeatedly raised and lowered to varying depths above 1000 m while under ship tow. Finestructure measu...
Oceanographic data from the last two decades show that the behavior of the East Australian Current system is qualitatively different on either side of a line extending south-southeast of Sugarloaf Poi...
Hydraulie Control and Flow Separation in a Multi-Layered Fluid with Applications to the Vema Channel
Hydraulie Control Multi-Layered Fluid Flow Separation
2009/2/5
Observations from a recent field experiment in the Vema Channel are briefly described. These show a remarkable change in the configuration of isopycnal surfaces within the channel and the development ...
Separation of an Inertial Boundary Current from a Curved Coastline
Inertial Boundary Current Curved Coastline
2009/1/10
A two-layer model is used to examine the separation of an inertial boundary current from a curved coastline and its subsequent path as a free jet. To isolate the inertial effect, the boundary current ...
Modulation of Gulf Stream Surface–Subsurface Frontal Separation by Path Curvature
Gulf Stream surface–subsurface frontal separation ubsurface-front path curvature
2009/1/7
Observations of surface–subsurface frontal separation have inconsistently demonstrated a relationship between surface–subsurface frontal separation and subsurface-front path curvature. An analytical m...
The Hydraulics of Local Separation in a Coastal Current with Application to the Kuroshio Meander
Local Separation Kuroshio Meander Coastal Current
2009/1/5
A hydraulic theory is advanced to explain the large sustained meandering of the Kuroshio Current to the south of Japan. It is shown that in general a promontory induces separation of a coastal current...
The Influence of Boundary Conditions on Midlatitude Jet Separation in Ocean Numerical Models
Boundary Conditions Midlatitude Jet Separation Ocean Numerical Models
2008/12/24
The separation Point of a midlatitude jet from the western boundary in ocean numerical models depends upon both the governing equations and the vertical coordinate used. Systematic differences in the ...
A Test of the Parsons–Veronis Hypothesis on the Separation of the Gulf Stream
Fleet Numerical Oceanography Center Gulf Stream Parsons–Veronis Hypothesis
2008/12/23
The Parsons–Veronis model, based on a two-layer wind-driven ocean, predicts the latitude at which the western boundary current separates from the western boundary. It has been tested on the Gulf Strea...
Boundary Current Separation in a Quasigeostrophic, Eddy-resolving Ocean Circulation Model
Boundary Current Quasigeostrophic Eddy-resolving Ocean Circulation Model
2008/12/22
The response of a rectangular, flat-bottom, eddy-resolving, quasigeostrophic ocean to a steady, double-gyre wind stress is studied to assess the sensitivity of the solutions to a partial-slip lateral ...
A Numerical Study of the Variability and the Separation of the Gulf Stream, Induced by Surface Atmospheric Forcing and Lateral Boundary Flows
Comprehensive Ocean-Atmosphere Data Set Gulf Stream
2008/12/22
A primitive equation regional model is used to study the effects of surface and lateral forcing on the variability and the climatology of the Gulf Stream system. The model is an eddy-resolving, coasta...
The Problem of Gulf Stream Separation：A Barotropic Approach
Gulf Stream Separation Barotropic Approach western boundary current
2008/12/19
Inertial separation of a western boundary current from an idealized continent is studied in a homogeneous ocean circulation model. A number of processes are identified that either encourage or prevent...
The Influence of Layer Outcropping on the Separation of Boundary Currents. Part I：The Wind-driven Experiments
zero wind-stress curl line Layer Outcropping Wind-driven Experiments
2008/12/18
The influence of outcropping isopycnal layers on the separation of western boundary currents is investigated in a series of wind-driven eddy-resolving multilayer primitive equation numerical experimen...
On the Separation of the Brazil Current from the Coast
low transport Brazil Current Coast
2008/12/17
A series of numerical experiments, using analytical and numerical models, leads to the conclusion that the separation of the Brazil Current from the coast can be related to the northward momentum of t...
