The Coastal Jet:Observations of Surface Currents Over the Oregon Continental Shelf From HF Radar
Coastal Jet Surface Currents Oregon Continental Shelf HF Radar
2015/8/10
The ocean circulation over the Oregon shelf during spring and summer is dominated by the effects of coastal upwelling. Equatorward winds drive an offshore Ekman transport in the surface layer, which p...
Stable Jet Modes：A Special Case of Eddy and Mean Flow Interaction
Stable Jet Modes Eddy Mean Flow Interaction
2009/2/23
The quasi-geostrophic, small-amplitude free modes of oscillation are examined for a midlatitude ocean basin with mean currents. Attention is restricted to a particular class of mean currents which are...
Topographically Induced Changes in the Structure of an Inertial Coastal Jet：Application to the Agulhas Current
Inertial Coastal Jet Agulhas Current
2009/2/13
Calculations are made of the changes in the structure of an inertial current which can be induced by slow changes in the topography of the continental shelf and slope along which it flows. The particu...
Mesoscale Eddies Detached from Spatially Growing Meanders in an Eastward-Flowing Oceanic jet Using a Two-Layer Quasi-Geostrophic Model
Mesoscale Eddies Eastward-Flowing Oceanic jet Two-Layer Quasi-Geostrophic Model
2009/2/10
The process of eddy detachment from a strong, eastward-flowing oceanic jet, which is modeled after the Gulf Stream, is studied using a two-layer quasi-geostrophic model. Numerical calculations are per...
Meanders and Detached Eddies of a Strong Eastward-Flowing Jet Using a Two-Layer Quasi-Geostrophic Model
Detached Eddies Two-Layer Quasi-Geostrophic Model Strong Eastward-Flowing Jet
2009/2/9
The process of meander growth on and eddy detachment from an eastward flowing oceanic jet, which is modeled after the Gulf Stream east of Cape Hatteras, is studied using numerical solutions of nonline...
Coastal Upwelling：Onshore–Offshore Circulation, Equatorward Coastal Jet and Poleward Undercurrent over a Continental Shelf-Slope
Coastal Upwelling Equatorward Coastal Jet Onshore–Offshore Circulation Poleward Undercurrent
2009/2/7
The onshore-offshore circulation, equatorward coastal jet and poleward undercurrent associated with coastal upwelling are studied with numerical models. The model ocean has a continental shelf-slope u...
A thin-jet model predicts the location of the axis of a strong current such as the Gulf Stream by using the vertical and cross-stream integrated vorticity balance, under the assumption that the meande...
Steady Wind-driven Upwelling in the Presence of a Baroclinic Coastally Trapped Jet
Wind-driven Upwelling Baroclinic Coastally Trapped Jet
2009/1/12
The usual two-layer model for steady wind-driven upwelling along a uniform coastline is extended to incorporate the effects of an upper-layer jet trapped against the coast. The characteristic width of...
Motivated by the observed branching of the Equatorial Undercurrent in the Gulf of Guinea, an idealized model is developed here to examine the termination of an equatorial jet in a gulf. Similarity sol...
Gulf Stream rings exhibit a number of propagation tendencies after their release from the current. Among those tendencies identified by observational, analytic, and numerical techniques are β-induced ...

Exact Repeat Mission Eddy Variability Seasonal Cycle Reynolds Stress
2008/12/30
Altimetric sea level data around the Kuroshio Extension, collected during the first year of the Geosat Exact Repeat Mission (ERM) (starting in November 1986), have been analyzed for energy propagation...
Estimating the Surface Transport of Meandering Oceanic Jet Streams from Satellite Altimetry：Surface Transport Estimates for the Gulf Stream and Kuroshio Extension

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 one-dimensional model of baroclinic instability is used to reconcile two differing interpretations on why neutrally buoyant floats cross the Gulf Stream more readily at subthermocline depths. The st...
