Equatorial Kelvin and Inertio-Gravity Waves in Zonal Shear Flow
Equatorial Kelvin Inertio-Gravity Waves Zonal Shear Flow
font style='font-size:12px;'>
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...
The Effects of Mean Shear Flow on Equatorial Basin Modes
Mean Shear Flow Equatorial Basin Modes
font style='font-size:12px;'>
2009/2/8
We test the sensitivity of energy trapping by equatorial basin modes to the presence of mean currents in a series of numerical experiments. At low frequency, trapping persists in the form of modified ...
On Stable and Unstable Rossby Waves in Non-Zonal Oceanic Shear Flow
Rossby Waves Non-Zonal Oceanic Shear Flow
font style='font-size:12px;'>
2009/2/7
We derive linear equations for the study of baroclinic instability of a non-zonal oceanic shear flow whose direction is allowed to change with depth. These equations can be used to study unstable dist...
Shear-Flow Dispersion, Internal Waves and Horizontal Mixing in the Ocean
Shear-Flow Dispersion Horizontal Mixing Internal Waves

wave are discussed. Our goal is to develop intuition about the role of such currents in horizontal ocean mixing through the mechanism of shear dispersion. The analysis suggests simple parameterization...
Lateral Wave Breaking and “Shingle” Formation in Large-Scale Shear Flow
Lateral Wave Large-Scale Shear Flow “Shingle” Formation
font style='font-size:12px;'>
2009/1/16
The temporal evolution of large amplitude quasi-geostrophic disturbances in a piecewise uniform potential vorticity flow is elucidated by numerical solutions of the “contour dynamica” equations. Later...
Reynolds Stresses and Secondary Circulation in a Stratified Rotating Shear Flow
Reynolds Stresses Secondary Circulation Stratified Rotating Shear Flow
font style='font-size:12px;'>
2008/6/23
A transverse secondary circulation should result from vertical mixing of momentum in a stratified shear flow influenced by the earth's rotation. A rigidly mounted acoustic Doppler current profiler was...
