On the Fraction of Internal Tide Energy Dissipated Near Topography
Internal tides have been implicated as a major source of mechanical energy for mixing in the ocean interior. Indeed, microstructure and tracer measurements have indicated that enhanced turbulence levels occur near topography where internal tides are generated. However, the details of the energy budget and the mechanisms by which energy is transferred from the internal tide to turbulence have be...

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 کاملDecay 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 کاملInternal wave attractors over random, small-amplitude topography
We consider whether small-amplitude topography in a two-dimensional ocean may contain internal wave attractors. These are closed orbits formed by the characteristics (or wave beam paths) of the linear, inviscid, steady-state Boussinesq equations, and their existence may imply enhanced scattering and energy decay for the internal tide when dissipation is present. We develop a numerical code to d...
