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...
Equatorial Kelvin and Inertio-Gravity Waves in Zonal Shear Flow
Equatorial Kelvin Inertio-Gravity Waves Zonal Shear Flow
2009/2/13
The interaction of geostrophic zonal mean currents in an equatorial ocean with free, neutrally stable, internal Kelvin and inertio-gravity waves is investigated using a two-layer, reduced-gravity mode...
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 ...
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...
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...
Topographic Scattering of Equatorial Kelvin Waves
Topographic Scattering Equatorial Kelvin Waves
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...
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...
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...
