Surface Thermal Boundary Condition for Ocean Circulation Models
Surface Thermal Boundary Condition Ocean Circulation Models
2009/3/9
By employing a heat budget analysis appropriate to zonally and time averaged conditions within the atmosphere, it is shown that the net downward heat flux Q at the ocean's surface can be expressed as ...
Circulation and c over the Ghana Continental Shelf during the 1974 Upwelling
Ghana Continental Shelf 1974 Upwelling 1974 Upwelling
2009/3/7
The changes in the circulation and hydrographic structure over the continental shelf south of Tema, Ghana, during the 1974 upwelling are described. For the first time in this region an Aanderaa curren...
The Noutidal Flow in the Providence River of Narragansett Bay：A Stochastic Approach to Estuarine Circulation
Noutidal Flow Narragansett Bay Providence River Estuarine Circulation
2009/3/7
Atmospherically driven flow in the Providence River (a partially mixed estuary) has been examined using a 51-day velocity record measured 2 m from the bottom. Velocity fluctuations at time scales betw...
Numerical Simulation of the Arctic Ocean Circulation
Numerical Simulation Arctic Ocean Circulation
2009/3/7
The circulation of the Arctic Ocean and Greenland Sea is simulated using the 1969 numerical model of Bryan and Cox. The coastline and bottom topography of the region are resolved by a 110 km horizonta...
A Zonally Uniform Regime in the Oceanic Circulation
Zonally Uniform Regime Oceanic Circulation
2009/3/7
The hypothesis of a zonally uniform regime for the interior oceanic circulation is advanced. The regime is found theoretically in frictional models, such as the one by Stommel (1948), when the meridio...
A Three-Dimensional Model of Lake Ontario's Summer Circulation I. Comparison with Observations
A Three-Dimensional Model Lake Ontario's Summer Circulation
2009/3/7
Observations of Lake Ontario during the International Field Year for the Great Lakes are used to develop a. three-dimensional numerical model for calculating temperature and current. The model has a v...
Eddies and the General Circulation of an Idealized oceanic Gyre：A Wind and Thermally Driven Primitive Equation Numerical Experiment
General Circulation Idealized oceanic Gyre Equation Numerical Experiment
2009/3/7
We present the results of a multi-level, constant depth, primitive equation general ocean numerical circulation simulation with mesoscale resolution. A single mid-latitude model gyre is driven by wind...
On the Characteristics and Circulation of the Southwestern Atlantic Ocean
North Atlantic Deep Water Circumpolar Water
2009/3/7
The waters found within the southwestern Atlantic Ocean extend into it as separate lavers with markedly different characteristics. Along the western boundary the deeper waters, derived from the North ...
Simulation of ozone production in a complex circulation region using nested grids
ozone production complex circulation region nested grids
2009/2/26
During the ESCOMPTE precampaign (summer 2000, over Southern France), a 3-day period of intensive observation (IOP0), associated with ozone peaks, has been simulated. The comprehensive RAMS model, vers...
A Three-Dimensional Model of Lake Ontario’s Summer Circulation. II. A Diagnostic Study
Three-Dimensional Model Diagnostic Study Summer Circulation
2009/2/23
A two-layer circular lake model is used to study the mean flow of Lake Ontario during midsummer. By computing the model only to the second order of amplitude, it is shown that the observed cyclonic ci...
The Circulation in the Gulf of Mexico Derived from Estimated Dynamic Height Fields
Dynamic Height Fields Gulf of Mexico
2009/2/23
Monthly mean dynamic height topographies for the upper 500 m of the Gulf of Mexico, seasonal mean topographies for the upper 1000 m and annual topographies for the deep flow are presented. The dynamic...
On the Mid-Depth Circulation of the North Pacific Ocean
Mid-Depth Circulation North Pacific Ocean
2009/2/23
The large-scale oxygen distribution within the upper 1500 m of the North Pacific Ocean reveals an extra zone of low oxygen near 30–40°N in the east that is not easily compatible with a simple large-sc...
The Near-Surface Circulation of the Eastern North Pacific
Near-Surface Circulation Eastern North Pacific
2009/2/23
A description of the near-surface circulation of the eastern North Pacific during 1976–77 is given. The data for the study are obtained from 23 satellite (Nimbus 6) tracked drifters. The large-scale d...
The Relationship of the Curl of the Local Wind Stress to the Circulation of the Cayman Sea and the Gulf of Mexico
Local Wind Stress Gulf of Mexico Cayman Sea
2009/2/23
The curl of the annual mean wind stress is proposed as the forcing mechanism for the anticyclonic gyre observed in the Cayman Sea. A simple wind-driven model is presented to illustrate how a steady-st...
