Decay of an internal tide due to random topography in the ocean
We present a theoretical and numerical study of the decay of an internal wave caused by scattering at undulating sea-floor topography, with an eye towards building a simple model in which the decay of internal tides in the ocean can be estimated. As is well known, the interactions of internal waves with irregular boundary shapes lead to a mathematically ill-posed problem, so care needs to be ta...
متن کاملParametric subharmonic instability of internal gravity wave beams
Internal gravity wave beams are time-harmonic plane waves with general spatial profile that arise in continuously stratified fluids owing to the anisotropy of this wave motion. In the last decade, these wave disturbances have been at the forefront of research, both from a fundamental perspective and in connection with various geophysical flow processes. Oceanic internal wave beams, in particula...
متن کاملa numerical study of internal tide generation due to interaction of barotropic tide with bottom topography in the oman gulf
a major part of tidal energy is usually dissipated by the interaction of tidal currents with bottom topography. gulf of oman is a marginal sea which has variable topography and its dominant tidal constituent is m2 semi-diurnal tide. in this paper, the interaction of barotropic tidal current with bottom topography is evaluated. this phenomenon causes the formation of internal tide. internal tide...
متن کاملThree-Dimensional Double-Ridge Internal Tide Resonance in Luzon Strait
The three-dimensional (3D) double-ridge internal tide interference in the Luzon Strait in the South China Sea is examined by comparing 3D and two-dimensional (2D) realistic simulations. Both the 3D simulations and observations indicate the presence of 3D first-mode (semi)diurnal standing waves in the 3.6-km-deep trench in the strait. As in an earlier 2D study, barotropic-to-baroclinic energy co...
متن کاملOn the Theory of the Diurnal Tide
Laplace's tidal equation for diurnal tides of longitudinal number one is investigated. It is found that in addition to the previously found solutions (Hough Functions) corresponding to positive equivalent depths there are also Hough Functions corresponding to negative equivalent depths. Both are necessary for the representation of observed tidal data. As an application of the Hough Functions th...
