A simple nonlinear model of the generation of Kelvin waves is presented and applied to internal Kelvin waves in Lake Michigan. It is shown that a Kelvin wave which has a wavelength longer than the Ros...
Coastal Upwelling and Kelvin Waves with Small Longshore Topography
Coastal Upwelling Kelvin Waves Small Longshore Topography
2009/2/23
A simple, uniformly stratified, linear model is developed to examine the effects on upwelling and internal Kelvin wave propagation of small, slow, longshore varying topography and coastline. The condi...
Observations of Internal Kelvin Waves Trapped Round Bermuda
Internal Kelvin Waves Trapped Round Bermuda
2009/2/18
Observations of the vertical and horizontal structure of motions near Bermuda have been made with two long-term moored arrays, one relatively far from and the other close to the island. Although not c...
Topographic Coupling of Surface and Internal Kelvin Waves
Topographic Coupling Surface Internal Kelvin Waves
2009/2/18
An analytical method is developed to compute the diffraction of a barotropic Kelvin wave by a localized topographic irregularity on an otherwise flat-bottom ocean with an arbitrary vertical stratifica...
An analytic theory is presented for free, barotropic Kelvin waves subject to constant, vertical eddy viscosity on a semi-infinite, f-plane shelf of constant depth bordering a straight, vertical coast....
Wind-Generated Equatorial Kelvin Waves Observed Across the Pacific Ocean
Sea-level fluctuations Zonal winds Pacific Ocean low-mode Kelvin waves
2009/2/6
Sea-level fluctuations during 1978–80 at equatorial Pacific islands separated by as much as one-quarter of the earth's circumference are coherent at periods of 1–6 weeks with phases implying eastward ...
On Vertically Propagating Coastal Kelvin Waves at Low Latitudes
internal Kelvin waves Low Latitudes
2009/2/5
Vertically propagating coastal internal Kelvin waves (IKWs) forward by the alongshore component of the wind at the coast are studied, utilizing an f-plane model of a continuously stratified ocean with...
The effect of a mean current on Kelvin waves is considered, including the case when the current is not in geostrophic balance. Because the problem is non-separable, a perturbation scheme is developed ...
Internal Kelvin Waves Generated by Quasi-Periodic Mesoscale Motion along the Coast
Internal Kelvin Waves Quasi-Periodic Mesoscale Motion Coast
2009/1/16
In a two-layer model with a rigid surface and a flat bottom on an f-plane, an internal Kelvin wave is forced by quasi-geostrophic, mesoscale meanders of a coastal current. These meanders are assumed t...
Adjustment of the Ocean under Buoyancy Forces. Part I：The Role of Kelvin Waves
Buoyancy Forces Kelvin Waves
2009/1/13
The early stages of the adjustment of an ocean toward equilibrium is examined using an ocean general circulation model. The initial state is one with uniform meridional potential temperature gradients...
The Interaction of Equatorial Kelvin Waves with Realistically Sheared Zonal Currents
Equatorial Kelvin Waves Realistically Sheared Zonal Currents
2009/1/13
We investigate the interaction of baroclinic equatorial Kelvin waves with realistically sheared background zonal currents in a linearized, continuously stratified model. The background flows are in th...

2009/1/6
We develop a linear, reduced-gravity model with two active layers above a deep, resting layer to examine the scattering of equatorial Kelvin waves from meridional submarine ridges. Model ridges, ideal...
Low-Frequency Reflection from a Nonmeridional Eastern Ocean Boundary and the Use of Coastal Sea Level to Monitor Eastern Pacific Equatorial Kelvin Waves
intertropical convergence zone Low-Frequency Reflection Equatorial Kelvin Waves
2008/12/22
Analytical theory and wind, sea level, and atmospheric pressure data were used to examine low-frequency dynamics near the equatorial eastern Pacific Ocean boundary. The analytical technique involves l...

Intraseasonal Kelvin Waves Equatorial Pacific Ocean
2008/12/18
Previous studies have shown that intraseasonal Kelvin waves are a prominent mode of variability in the eastern and central equatorial Pacific. These waves appear to be remotely forced by wind variatio...
Propagation and Breaking of Nonlinear Kelvin Waves
Nonlinear Kelvin Waves Klein-Gordon equation
2008/12/12
The evolution of nonlinear Kelvin waves is studied using analytical and numerical methods. In the absence of dispersive (nonhydrostatic) effects, such waves may evolve to braking. The authors find tha...
