Harmonic Generation of Shallow Water Waves Over Topography
Harmonic Generation Shallow Water Waves Topography
2009/4/3
We investigate the reflection and nonlinear interaction between the first and second harmonics of a two-dimensional Boussinesq wavetrain. Effects of topography are included, the depth departing from a...
Currents [O(0.1 m sec−1)] and sea-level variations [O(0.1 m)] on the continental shelf can be produced when atmospheric disturbances pass by. Since the atmospheric systems have length scales lar...
On the Generation of Mesoscale Eddies and their Contribution to the Oceanic General Circulation. II. A Parameter Study
Mesoscale Eddies Oceanic General Circulation Parameter Study
2009/3/24
In this investigation the wind-driven ocean circulation theories are extended to include mesoscale eddies as an integral part of the general circulation of the ocean. A two-layer numerical model of oc...
On the Generation of Mesoscale Eddies and their Contribution to the Oceanic General Circulation. I. A Preliminary Numerical Experiment
Mesoscale Eddies Oceanic General Circulation Preliminary Numerical Experiment
2009/3/24
Numerical experiments on the wind-driven ocean circulation in a closed basin show that mesoscale eddies can appear spontaneously during the integration of the equations of motion for a baroclinic ocea...
On the Generation of Baroclinic Rossby Waves in the Ocean by Meteorological Forces
Baroclinic Rossby Waves Meteorological Forces
2009/3/7
The generation of baroclinic Rossby waves in a continuously stratified ocean by fluctuating fields of wind stress, buoyancy flux and atmospheric pressure at the sea surface is studied by means of boun...
The dynamics of downwelling fronts observed along the steep and elongated southern shore of Lake Ontario are investigated by considering the nonlinear response to surface forcing of one-layer and two-...
An analytical and experimental study of the baroclinic waves generated by a monopole dislocation of the sea floor is presented. Analytical results are based on a two-dimensional and linearized descrip...
Generation and Propagation of 30-Day Waves in a Numerical Model of the Pacific
30-Day Waves Numerical Model the Pacific
2009/2/18
A multilevel numerical model is applied to the equatorial Pacific Ocean, driven by long-term averaged, monthly varying winds. In agreement with satellite-observed sea surface temperatures, the solutio...
On the Generation of Geostrophic Eddies by Surface Buoyancy Flux Anomalies
Geostrophic Eddies Surface Buoyancy Flux Anomalies
2009/2/13
Stochastic fluctuations in the buoyancy flux at the air-sea interface create density anomalies in the oceanic surface layer, which drive quasi-geostrophic motions in the ocean interior. The efficiency...
The Generation of Continental Shelf Waves by Alongshore Variations in Bottom Topography
Continental Shelf Waves Alongshore Variations Bottom Topography
2009/2/13
The effects of alongshore variations in bottom topography on wind-stress-forced barotropic motion over a continental shelf and slope are studied. An idealized channel model with a weakly sloping botto...
In this paper a mechanism is proposed which could be responsible for the formation of sharp horizontal density gradients such as those observed in shallow seas, from fluid which initially has weak hor...
Effects of Density Front on the Generation and Propagation of Internal Tides
Density Front Internal Tides
2009/2/10
A numerical model is developed to study the internal tidal motion on the continental margin. The system includes irregular bottom topography and a horizontal density stratification maintained by a mea...
The Estimation of Wind-Wave Generation in a Discrete Spectral Model
Wind-Wave Generation Discrete Spectral Model
2009/2/9
The estimation of wind-wave generation using a new discrete spectral model is compared to Hasselmann et al.'s (1976) parametric model and to models driven primarily by direct transfer of energy from t...
Momentum and Energy Transfer in Wind Generation of Waves
Momentum Wind Generation Energy Transfer
2009/2/8
Complete expressions for wind momentum and energy transfer to wind-generated waves are derived based on a boundary-layer integral method. The airflow and wave measurements as made by Wu et al. (1977, ...

Cyclonic Ring Drake Passage
2009/2/7
An equatorward meander in the Antarctic Polar Front at Drake Passage was observed to amplify and pinch off during January and early February 1979, forming a cold-core. cyclonic current fins with a rad...
