Extent and Energetics of the Hawaiian Lee Countercurrent
Hawaiian Lee Countercurrent Extent and Energetics
2015/7/16
Direct velocity observations from drogued drifters in the Hawaiian Island region are used to map the time-mean and seasonal variability of the Hawaiian Lee Countercurrent (HLCC). The density of these ...
Variability of Near-Surface Currents in the Atlantic North Equatorial Countercurrent during GATE
Near-Surface Currents GATE Atlantic North Equatorial Countercurrent
2009/2/18
Measurements of wind at 5 m height, currents at 7.6, 15.4. 21.4 and 27.5 m depths, and temperature at 19 depths between 0.4 and 43.3 m depths were made from 19 August to 12 September 1974 at 8°41′N, 2...
The Forced Annual Reversal of the Atlantic North Equatorial Countercurrent
North Equatorial Countercurrent Atlantic North Equatorial Countercurrent
2009/2/6
We analyze the variability of the thermal structure associated with the Atlantic North Equatorial Countercurrent (NECC) and its relation to the seasonally varying winds. The analysis performed all...
On the Maintenance of the Subtropical Front and its Associated Countercurrent
Subtropical Front wind-driven circulation thermally driven flow
2009/1/20
In the North Pacific and Atlantic Oceans, the Subtropical Countercurrent is an eastward flow across the Subtropical Gyre at a latitude where a classical wind-driven circulation theory would predict a ...
Numerical Study of the Seasonal Variations of the Subtropical Front and the Subtropical Countercurrent
Numerical Study Seasonal Variations Subtropical Front Subtropical Countercurrent
2009/1/12
Response of the Subtropical Countercurrent and the Subtropical Front in the North Pacific Ocean to seasonally changing wind stress and thermal condition are examined using the same idealized numerical...
Coastal Countercurrent and Mesoscale Eddy Formation by Tidal Rectification near an Oceanic Cape
Coastal Countercurrent Mesoscale Eddy Formation Tidal Rectification Oceanic Cape
2009/1/9
Cape St. James is an extensive triangular-shaped promontory located in a tidally energetic region at the southern tip of the Queen Charlotte Islands approximately 150 km off the mainland coast or Brit...
New light is shed on Worthington's concept of the North Atlantic circulation, postulating the existence of two anticyclonic gyres. This concept, which seems to have been laid to rest in the last decad...
An Interannual Study of the Atlantic North Equatorial Countercurrent
Atlantic North Equatorial Countercurrent Inverted Echo Sounders sea surface
2008/12/17
Beginning in 1983, the dynamic height difference at the sea surface defining the countercurrent trough at 38°W was continuously observed by Inverted Echo Sounders at 3°N and 9°N for six years and ten ...
Seasonal Eddy Field Modulation of the North Pacific Subtropical Countercurrent: TOPEX/Poseidon Observations and Theory
Seasonal Eddy Field Modulation North Pacific Subtropical Countercurrent TOPEX
2008/7/22
Altimetry data from the first 5¼-yr TOPEX/Poseidon mission (October 1992–December 1997) are analyzed focusing on the North Pacific Subtropical Countercurrent (STCC) near the center of the Pacif...
Subtropical Countercurrent in an Idealized Ocean GCM
Subtropical Countercurrent Idealized Ocean GCM
2008/7/11
In the North Pacific, there is a shallow eastward current called the subtropical countercurrent, which flows across the central subtropical gyre. The present article studies the generation mechanism o...
Ventilated Thermocline Strongly Affected by a Deep Mixed Layer: A Theory for Subtropical Countercurrent
Ventilated Thermocline Deep Mixed Layer Subtropical Countercurrent
2008/7/11
The mixed layer thickness generally increases in the northward direction, but its change seems to occur rather sharply in a narrow transition zone, referred to as a mixed layer front here. The author ...
Numerical Simulations of a Buoyancy-Driven Coastal Countercurrent off Vancouver Island
Numerical Simulations Buoyancy-Driven Coastal Vancouver Island
2008/7/8
A three-dimensional prognostic numerical model has been developed to study the ocean circulation around Vancouver Island, British Columbia. In a series of simulations, the model is applied to examine ...
Influence of Equatorial Dynamics on the Pacific North Equatorial Countercurrent
