Some Aspects of Gulf Stream Western Boundary Eddies from Satellite and In Situ Data
Gulf Stream Western Boundary Eddies Satellite In Situ Data
2009/2/19
NOAA-5 infrared images were used to determine statistics of existing and developing perturbations on the western boundary of the Gulf Stream. The satellite data were combined with oceanographic data t...
Coastal-Trapped and Frontal-Trapped Waves in a Baroclinic Western Boundary Current
Coastal-Trapped Frontal-Trapped Waves Baroclinic Western Boundary Current
2009/2/19
Four types of stable, subinertial Rossby-like waves have been found to propagate alongshore in a model baroclinic boundary current similar to the Gulf Stream as it flows along the continental margin o...
Can the Western Boundary Layer Affect the Potential Vorticity Distribution in the Sverdrup interior of a Wind Gyre?
Western Boundary Layer Potential Vorticity Wind Gyre
2009/2/6
The question posed in the title of this paper is answered in the affirmative by investigating a two-layer, quasi-geostrophic model of the wind-driven circulation. The two layers model the thermocline ...
Mean Flow and Variabilities in the Deep Western Boundary Current
Deep Western Boundary Current Mean Flow
2009/1/21
The Deep Western Boundary Current (DWBC or Western Boundary Undercurrent) was observed for over 100 days by an L-shaped array of current meters along and across the Blake Escarpment. The measurements ...
Two tritium sections through the deep western boundary current east of the Bahamas taken in late 1980 and early 1981 are presented. Tritium from the bomb tests in the late 1950s and early 1960s is use...
Interannual Variability of the Kuroshio Frontal Structure along Its Western Boundary in the North Pacific Ocean Associated with the 1982 ENSO Event
Interannual Variability North Pacific Ocean Kuroshio Frontal Structure
2009/1/8
The vertically averaged temperature (Tav) over the upper 200 m of ocean in the western boundary of the North Pacific is used to detect changes in the strength and path of the Kuroshio Front along the ...
Determining the Strength of the Deep Western Boundary Current Using the Chlorofluoromethane Ratio
chloro fluoro methanes Deep Western Boundary Current
2009/1/4
The dilution of a passive tracer during deep water formation and the subsequent advection/mixing in a deep boundary current is modeled with application to chlorofluoromethanes (CFMs) in the North Atla...
Energy Dissipation and Upwelling in a Western Boundary Current
Energy Dissipation Upwelling Western Boundary Current
2008/12/30
Energy dissipation in a western boundary current begins with the conversion of mean potential energy into kinetic energy of “primary” eddies. The rate of this energy conversion is taken to equal the t...
The Role of the Western Boundary in the ENSO Cycle：Experiments with Coupled Models
El Niñ o–Southern Oscillation Western Boundary Coupled Models
2008/12/30
Coupled models of the Pacific ocean–atmosphere system have been shown to produce oscillations in the model coupled system that resemble the observed El Niño–Southern Oscillation (ENSO) cycle in...
Potential Vorticity Sources and Sinks in a Quasi-geostrophic Ocean：beyond Western Boundary Currents
eddy-resolving general circulation model Potential Vorticity Sources Quasi-geostrophic Ocean
2008/12/30
Potential vorticity dynamics for a quasi-geostrophic eddy-resolving general circulation model (EGCM) are studied in order to determine the effects of mesoscale variability on the potential vorticity d...
Matching a Ventilated Thermocline Model with Inertial Western Boundary Currents
Ventilated Thermocline Model Inertial Western Boundary Currents western boundary region
2008/12/30
A two-layered ventilated thermocline model is matched with inertial western boundary currents in the southern part of the western boundary region. For general cases the western boundary currents break...
