Over fifty years ago, Carl Eckart described the sequence of processes as a passive scalar is stirred and mixed in a turbulent flow (Eckart, 1948). At first, during the stirring phase, the variance of ...
Upwelling and Coastal Jets in a Continuously Stratified Ocean
Coastal Jets Continuously Stratified Ocean Upwelling
2009/4/2
A simple, linear, two-dimensional, f-plane model of coastal upwelling in a continuously stratified ocean is investigated. The transient response of the fluid to an impulsively applied alongshore wind ...
Upwelling Layers in a Steady, Wind-Driven Stratified Ocean
Upwelling Layers Wind-Driven Stratified Ocean
2009/4/2
A theoretical study is made of a region of steady upwelling adjacent to the eastern boundary of a stratified ocean. A multi-layered structure is required to satisfy all the boundary conditions. The ve...
A two-layer model is used to study the properties of free coastal trapped waves which propagate over an idealized continental shelf and continental slope bottom topography. With both stratification an...
Coastal-Trapped Waves in a Continuously Stratified Ocean
Coastal-Trapped Waves Continuously Stratified Ocean
2009/3/7
The theory of coastal-trapped waves is extended to include the general features of continuous density stratification, variable bottom topography, and a finite coastal wall. In the limit of a vanishing...
Propagation of Coastal-Trapped Waves at Low Latitudes in a Stratified Ocean with Continental Shelf Slope
Coastal-Trapped Waves Continental Shelf Slope Low Latitudes
2009/2/10
Poleward propagation of coastal-trapped waves induced by a baroclinic equatorial Kelvin wave incident on the eastern boundary is studied in numerical models. When the thermocline is shallower than she...
Quasi-Geostrophic Waves in a Stratified Ocean with Bottom Topography
upper layer component lower layer component Quasi-Geostrophic Waves
2009/2/9
Quasi-geostrophic waves in a two-layer ocean with bottom topography on a β-plane are examined in detail. The bottom slopes in an arbitrary direction but gently and uniformly. A clear understanding of ...
Sampling Turbulence in the Stratified Ocean:Statistical Consequences of Strong Intermittency
Stratified Ocean Statistical Consequences Strong Intermittency
2009/1/8
Turbulence and turbulent mixing in the ocean are strongly intermittent in amplitude, space and time. The degree of intermittency is measured by the “intermittency factor” σ2, defined as either σ2ln, t...
Unsteady Abyssal Circulation Driven by a Discrete Buoyancy Source in a Continuously Stratified Ocean
Circulation Driven Discrete Buoyancy Source Stratified Ocean
2008/11/24
Analytical and numerical models are presented for linear quasigeostrophic buoyancy-driven flow forced bya time periodic pulsating point mass source in a continuously stratified, incompressible β-plane...
Evolution of Long Planetary Wave Packets in a Continuously Stratified Ocean
Long Planetary Wave Continuously Stratified Ocean
2008/7/2
Recent TOPEX/Poseidon observations show an enhanced (weakened) westward propagation of long planetary Rossby waves at extratropics (Tropics) and they usually propagate faster in the western basin than...
Instability of Abyssal Currents in a Continuously Stratified Ocean with Bottom Topography
Abyssal Currents Continuously Stratified Ocean Bottom Topography
2008/6/25
A theory is developed for the baroclinic destabilization of density-driven abyssal flows over topography in a rotating environment. The dominant instability mechanism being studied is the release of a...
