Initial Testing of a Numerical Ocean Circulation Model Using a Hybrid (Quasi-Isopycnic) Vertical Coordinate
Initial Testing Hybrid (Quasi-Isopycnic) Vertical Coordinate Numerical Ocean Circulation Model
2009/2/9
An ocean circulation model, developed for the study of mesoscale to gyre-scale circulation and heat transport, is described and tested. The model employs density as vertical coordinate except in the i...
Development of a Three-Dimensional, Limited-Area (Island) Shelf Circulation Model
Three-Dimensional Limited-Area (Island) Shelf Circulation
2009/2/7
A three-dimensional, finite-difference model is developed to study limited-area (island) shelf circulation. The model uses a semi-implicit scheme in the cross-shore dimension and a mode-splitting tech...
An Eclectic Atlantic Ocean Circulation Model. Part I：The Meridional Flux of Heat
Atlantic Ocean Circulation Model Meridional Flux Heat
2009/1/21
A model of the Atlantic has been formulated that combines ordinary quasi-geostrophic constraints (based upon the dynamic method and Ekman layer) with a great variety of additional information availabl...
A Vertically Averaged Circulation Model Using Boundary-Fitted Coordinates
Boundary-Fitted Coordinates Vertically Averaged Circulation Model
2009/1/20
A two-dimensional vertically averaged circulation model using boundary-fitted coordinates has been developed for predicting sea level and currants in estuarine and shelf waters. The basic idea of the ...
The Use of Land and Sea Based Wind Data in a Simple Circulation Model
South Atlantic Bight Simple Circulation Model Wind Data
2009/1/19
The use of land based wind data in nearshore oceanographic work is common, but these winds do not accurately reflect coastal oceanic winds. Ocean winds are often underestimated by a factor of 2 and di...
A Ventilated Middepth Circulation Model for the Eastern North Atlantic
Ventilated Middepth Circulation Model Eastern North Atlantic
2009/1/10
A mechanism is proposed, based on the assumption of ventilation, to explain the middepth northward flow observed in the North Atlantic. The main feature of the solution is that the outcropping line of...
Initial Conditions for a General Circulation Model of Tropical Oceans
Initial Conditions General Circulation Model Tropical Oceans
2009/1/6
A general circulation model of the tropical Pacific Ocean, which realistically simulates El Niño of 1982–83, has been used to determine how different initial conditions affect the model. Given ...
A General Circulation Model for Upper Ocean Simulation
General Circulation Model Upper Ocean Simulation
2009/1/6
A general circulation model (GCM) of the ocean that emphasizes the simulation of the upper ocean has been developed. This emphasis is in keeping with its future intent, that of an air-sea coupled mode...

Quasi-Geostrophic Circulation Northeast Pacific Preliminary Numerical Experiment
2009/1/6
A limited-area quasi-geostrophic numerical model with mesoscale resolution is developed to study the circulation in the northeast (NE) Pacific Ocean. The model domain extends from the British Columbia...
An Intercomparison of Inverse Methods Using an Eddy-Resolving General Circulation Model
Inverse Methods Eddy-Resolving General Circulation Model
2009/1/6
Three inverse methods (the Bernoulli, beta-spiral, and box inverse methods) are used on mean data from an eddy-resolving oceanic general circulation model, in an attempt to reconstruct the observed me...
