Effect of Local Bottom Slope and Roughness Coefficient Variations in Overland Flows
Local Bottom Slope Roughness Coefficient Variations Overland Flows
2009/10/28
The investigation analyses the effects of local bottom slope and roughness
coefficient variations in overland flow over a plane by using the kinematic
wave theory. Results are compared with the usua...
Longshore Currents and the Onset of Upwelling over Bottom Slope
Longshore Currents Onset of Upwelling Bottom Slope
2009/3/26
The evolution of longshore currents produced by upwelling on an f-plane over shelf-like bottom topography for times long compared to a barotropic spin-up time, but short compared to a diffusion time, ...
Some Observations of Baroclinic Diurnal Tides over a Near-Critical Bottom Slope
Baroclinic Diurnal Tides Baroclinic Diurnal Tides
2009/2/19
The time-depth structure of the baroclinic diurnal tide has been examined with the aid of current and temperature profiles on the West Florida Continental Shelf. Of interest is the fact that the diurn...
On the Stability of a Fluid with Specialized Density Stratification. Part I：Baroclinic Instability and Constant Bottom Slope
Specialized Density Stratification Baroclinic Instability Constant Bottom Slope
2009/2/16
A three-layer model is used to study the stability of large-scale oceanic zonal flows over topography. The mean density profile employed has upper and lower layers of constant densities ρ1* and ρ3*, r...
Linear Instability of a Current Flowing Along a Bottom Slope Using a Three-Layer Model
Linear Instability Current Flowing Bottom Slope Using Three-Layer Model
2009/1/22
A quasi-geostrophic model of a three-layer fluid on an f-plane is employed to study instability of a current flowing over a uniform bottom slope with isobaths parallel to the current. The model has a ...
Pedlosky's theory explaining the behavior of unstable baroclinic waves in the β-plane is modified to include a sloped bottom (although the β effect is ignored). The result found is the same sort of no...
Inertial Boundary Layer with a Velocity Front：HOW the Bottom Slope Controls the Western Boundary Current Path
Inertial Boundary Layer Velocity Front Bottom Slope Western Boundary Current Path
2008/12/11
The western boundary current of the subtropical gyre flows on the upper continental slope and is controlled by the bottom topography; however, our theoretical understanding of how the path of the boun...
Inertial Western Boundary Current on a Bottom Slope：Effects of Horizontal Viscosity and Inshore Conditions
Numerical model Horizontal Viscosity Inshore Conditions
2008/12/3
The author investigates how the path of the subtropical inertial western boundary current on a bottom slope is affected by viscosity, coastal boundary condition, and width of the continental shelf.
Influence of a Strong Bottom Slope on the Evolution of a Surface-Intensified Vortex
Strong Bottom Slope Surface-Intensified Vortex
2008/7/10
The authors investigate the influence of steep bottom topography on the propagation of a vortex in a two-layer quasigeostrophic model. The vortex is intensified in the upper layer and the planetary be...
