An Inertial Model of Steady Coastal Upwelling
Inertial Model Steady Coastal Upwelling
font style='font-size:12px;'>
2009/2/23
A nonlinear inertial model of a steady-state coastal upwelling circulation is presented. The model describes a longshore equatorward current and countercurrent structure which is independent of any pa...
A Model and Observations of Time-Dependent Upwelling over the Mid-Shelf and Slope
Time-Dependent Upwelling Mid-Shelf Slope
font style='font-size:12px;'>
2009/2/19
A simple model of time-dependent quasi-geostrophic upwelling over an outer continental shelf and slope region is considered with the velocity assumed independent of the alongshore coordinate The flow ...
The Influence of Bottom Topography on Upwelling off Peru
Bottom Topography Upwelling off Peru
font style='font-size:12px;'>
2009/2/18
The x-y-t, two-layer β-plane numerical model developed by Hurlburt (1974) is used to examine the upwelling system off Peru. The region off Peru from 14 to 15°30's is one of strong and persistent upwel...
On the Theory of Coastal-Trapped Waves in an Upwelling Frontal Zone
Coastal-Trapped Waves Upwelling Frontal Zone
font style='font-size:12px;'>
2009/2/16
Free, stable, coastal-trapped waves propagating in a continental shelf regime typical of coastal upwelling areas are studied using a two-layer analytical model. Two cases of interfacial geometry and m...
The Role of Wind-Generated Mixing in Coastal Upwelling
Wind-Generated Mixing Coastal Upwelling
font style='font-size:12px;'>
2009/2/10
A simple parameterization of mixing processes originally developed by Kraus and Turner (1967) is included in a two-dimensional, two-layer theory of wind-driven coastal upwelling. Mixed-layer deepening...
An Estimate of Equatorial Upwelling in the Pacific
Equatorial Upwelling the Pacific cool water
font style='font-size:12px;'>
2009/2/10
Upwelling in the equatorial Pacific Ocean manifests itself by a tongue of cool water stretching from the Galapagos Islands to the date line. To estimate the rate of upwelling, the mass, heat and salt ...
A Two-Dimensional Diabatic Isopycnal Model—Simulating the Coastal Upwelling Front
Coastal Upwelling Front Two-Dimensional Diabatic Isopycnal Model—Simulating
font style='font-size:12px;'>
2009/2/9
A two-dimensional diabatic isopycnal model is designed to study coastal upwelling. The diabatic effect is represented by vertical mixing of the density field. Vertical eddy coefficients are determined...
Transient Upwelling Generated by Two-Dimensional Atmospheric Forcing and Variability in the Coastline
Transient Upwelling Variability Two-Dimensional Atmospheric Forcing
font style='font-size:12px;'>
2009/2/8
The present paper deals with two-dimensional transient upwelling in a two-layer ocean of constant depth. Motions generated by several two-dimensional atmospheric forcings are investigated. Using asymp...
Eastern Boundary Currents and Coastal Upwelling

font style='font-size:12px;'>
2009/2/8
The adjustment of the eastern coastal zone of an inviscid ocean with vertical walls to a change in wind conditions occurs in two stages. After the propagation of a Kelvin wave across the forced region...
Coastal Upwelling：Onshore–Offshore Circulation, Equatorward Coastal Jet and Poleward Undercurrent over a Continental Shelf-Slope
Coastal Upwelling Equatorward Coastal Jet Onshore–Offshore Circulation Poleward Undercurrent
font style='font-size:12px;'>
2009/2/7
The onshore-offshore circulation, equatorward coastal jet and poleward undercurrent associated with coastal upwelling are studied with numerical models. The model ocean has a continental shelf-slope u...
