The Nonlinear Equatorial Kelvin Wave
Nonlinear Equatorial Kelvin Wave leading edge Guinea upwelling
2009/2/16
Using the method of strained coordinates, a uniformly valid approximation to the nonlinear equatorial Kelvin wave is derived. It is shown that nonlinear effects are negligible for the Kelvin waves ass...
The Free Kelvin Wave with Lateral and Vertical Viscosity
Free Kelvin Wave Lateral Vertical Viscosity
2009/2/6
Free Kelvin wave solutions of the linear shallow-water equations are described, for an f-plane. Lateral and vertical viscous effects are represented by terms ν2u and du, respectively, where (u,v) is t...
The Free Kelvin Wave in Finite-Difference Numerical Models
Free Kelvin Wave Finite-Difference Numerical Models
2009/2/6
The effects of viscosity and finite- differencing on free Kelvin waves in numerical models (which employ the Arakawa B- or C-grid difference schemes) are investigated using the f-plane shallow-water e...
Interior Reflections of a Periodically Forced Equatorial Kelvin Wave
Interior Reflections Equatorial Kelvin Wave
2009/1/16
A fully three-dimensional, wind-forced equatorial model is used to study the effects of the strong near- surface equatorial pycnocline on energy transmission into the deep ocean. The equatorial Kelvin...
Kelvin Wave Propagation in a High Drag Coastal Environment
Kelvin Wave Propagation High Drag Coastal Environment
2009/1/6
Coastally trapped Kelvin waves in a model system of a flat half-planar ocean with a high-drag region of width L adjacent to the coast have properties that depend on L, and its drag, D0. For L less tha...
Wind Forced Wave–Mean Flow Interactions in the Equatorial Waveguide. Part I：The Kelvin Wave
equatorial current system Kelvin Wave Equatorial Waveguide
2009/1/6
A numerical model is designed to study the effects of the strong, near-surface associated with the equatorial current system on energy transmission of time-periodic equatorial waves into the deep mean...
Transmission of a Two-Layer Coastal Kelvin Wave over a Ridge
Two-Layer Coastal Kelvin Wave topographic ridge
2009/1/4
We consider the problem of a low-frequency, two-layer, coastal Kelvin wave which impinges on a topographic ridge or valley at some angle to the coastline, with the aim of bounding the transmission of ...
How Much of a Baroclinic Coastal Kelvin Wave Gets over a Ridge?
Baroclinic Coastal Kelvin Wave bottom-trapped low-frequency
2008/12/30
This paper considers the interaction between a bottom-trapped low-frequency, reduced-gravity maid Kelvin wave propagating along a coastal wall, and a smooth ridge extending away from the coastline. Al...
Propagation of an Equatorial Kelvin Wave in a Varying Thermocline
Equatorial Kelvin Wave Varying Thermocline
2008/12/30
We look at the effect of a slow zonal variation in thermocline depth on the propagation of a finite-amplitude Kelvin wave pulse in a single layer model. Dispersive effects are included by also allowin...
Coupled Kelvin-Wave and Mirage-Wave Instabilities in Semigeostrophic Dynamics
Coupled Kelvin-Wave Semigeostrophic Dynamics Mirage-Wave Instabilities
2008/10/31
A weak instability mode, associated with phase-locked counterpropagating coastal Kelvin waves in horizontal anticyclonic shear, is found in the semigeostrophic (SG) equations for stratified flow in a ...
Rossby Wave–Coastal Kelvin Wave Interaction in the Extratropics. Part I: Low-Frequency Adjustment in a Closed Basin
Rossby Wave–Coastal Kelvin Wave Interaction Low-Frequency Adjustment Closed Basin
2008/7/22
The interaction of open and coastal oceans in a midlatitude ocean basin is investigated in light of Rossby and coastal Kelvin waves. The basinwide pressure adjustment to an initial Rossby wave packet ...

Rossby Wave–Coastal Kelvin Wave Interaction Island Circulation
2008/7/22
The formation of an island circulation is investigated both theoretically and numerically in light of the dynamics of coastal Kelvin waves and Rossby waves. An island circulation is formed in three st...
