A Simple Model of Coastal Upwelling Dynamics
Coastal Upwelling Dynamics surface wind stress
2009/3/9
As a step in understanding the complicated dynamics of coastal upwelling areas, a simple theoretical model is examined. The motion is driven by surface wind stress acting on homogeneous water of const...
A linear model of the thermocline is examined for an ocean bounded by both eastern and western coasts. The analysis is carried out on a β-plane for an ocean in which diffusion of heat but not of momen...
Tidal Exchange through a Strait：A Numerical Experiment Using a Simple Model Basin
Tidal Exchange Simple Model Basin Strait
2009/2/19
In order to investigate the mechanism of tidal exchange through a strait, we numerically track the Lagrangian movement of water particles over a full cycle of the M2 tide. As a result, it is found tha...
Boundary-Forced Planetary Waves：A Simple Model Mid-Ocean Response to Strong Current Variability
Boundary-Forced Planetary Waves Mid-Ocean Response Strong Current Variability
2009/2/13
A simple linear model of the barotropic basin response to forcing imposed along the northern boundary is described. The dependence on latitude of the response may include oscillatory behavior or not, ...
The Effect of the Oceanic Boundary Layer on the Mean Drift of Pack Ice：Application of a Simple Model
Oceanic Boundary Layer Pack Ice Mean Drift
2009/2/13
Smoothed records of ice drift, surface wind and upper ocean currents at four manned stations of the 1975–76 AIDJEX experiment in the central Arctic have been analyzed to provide a statistical relation...
A Simple Model of Fjord and Coastal Circulation Interaction
Simple Model Fjord Coastal Circulation Interaction
2009/2/10
The dynamical interaction of a narrow fjord with a wind-driven coastal regime is investigated using a linear, two-layer numerical model. The Coriolis acceleration is important in the coastal regime bu...
A Simple Model for Stratified Shelf Flow Fields with Bottom Friction
Flow Fields Bottom Friction stratified shelf flow
2009/1/20
The effect of bottom friction on the subinertial frequency motion of stratified shelf flow fields is studied in a two-layer f-plane model with idealized shelf and slope bottom topography. Coastal-trap...
A Simple Model of the Formation and Maintenance of the Shelf/Slope Front in the Middle Atlantic Bight
Shelf/Slope Front Middle Atlantic Bight
2009/1/12
The strong salinity and temperature gradients across the shelf/slope front in the Middle Atlantic Bight often compensate such that the cross-front density gradient is nearly eliminated. The suggests t...
A Simple Model of the Wind-Driven Tropical Ocean
Wind-Driven Tropical Ocean pressure field geostrophic subsurface currants
2009/1/9
A simple analytic theory for some aspects of the wind-driven circulation in the tropical oceans is described. The nearly geostrophic subsurface currants and the pressure field are studied by means of ...
Simple Model of Abyssal Circulation, Including Effects of Wind, Buoyancy and Topography
Abyssal Circulation Topography Buoyancy Wind
2008/12/30
We examine problems of steady abyssal circulation using an inviscid planetary geostrophic layered model. The model includes an active wind-driven upper layer and arbitrary topography; forcing is in th...
A Simple Model of the Indonesian Throughflow and Its Composition
Indonesian Throughflow Papua New Guinea South Pacific North Pacific origin North Equatorial Countercurrent
2008/12/19
A simple analytical model of the closure of the wind-driven gyres in the tropical west Pacific is developed to illustrate the role of Halmahera and variations in the Pacific wind stress on the water m...
A Simple Model for the Shear-induced Decay of an Internal Solitary Wave
Internal solitary waves hear-induced Decay
2008/12/19
Internal solitary waves (ISWs) are a common feature of the coastal zone and marginal seas, especially close to shelf breaks, and are observed to mix the water column at the depth of maximum density gr...
A Simple Model of Mass-driven Abyssal Circulation over a General Bottom Topography
Mass-driven Abyssal Circulation General Bottom Topography
2008/12/18
The classic Stommel–Arons problem is revisited in the context of a basin with a general bottom topography containing an equator. Topography is taken to be smoothly varying and, as such, there are no v...
A Simple Model of the Mass Exchange between the Subtropical and Tropical Ocean
Mass Exchange Subtropical Tropical Ocean
2008/12/16
A simple ventilated thermocline model is used to study the subtropical-tropical mass exchange. It is found that the water subducted in the western subtropical gyre (recirculating window) tends to reci...
A Simple Model of Abyssal Circulation in a Circumpolar Ocean

2008/12/15
A simple barotropic model of abyssal circulation in a circumpolar ocean basin is constructed. In the presence of a sufficiently high ridge, the classical Stommel and Arons theory applies here with ver...
