Wave scattering by undulating bed topography in a two-layer ocean
two-layer ocean wave scattering bottom undulations reflection transmission coefficients
2011/9/13
The problem of wave scattering by undulating bed topography in a two-layer ocean is investigated on the basis of linear theory. In a two-layer fluid with the upper layer having a free surface, there e...
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...
Longshore Currents, Upwelling and Bottom Topography
Longshore Currents Bottom Topography Upwelling
2009/3/26
The effect of shelf-like bottom topography on a steady, linear, stratified, three-dimensional model of coastal upwelling is examined. It is shown that the presence of the bottom slope 1) reduces the r...

2009/3/24
A two-layer model is constructed for wind-driven flow over topography in a closed polar basin where the variation of Coriolis force with latitude is negligible. The model equations are reduced using s...
Fluctuations of the Dynamic Topography in the Pacific Ocean
Dynamic Topography Pacific Ocean
2009/3/24
The dynamic topography of the Pacific Ocean has been mapped and its mean annual and random variability has been investigated using approximately 66,600 hydrographic stations. Largest annual fluctuatio...
