Harmonic generation by reflecting internal waves
The generation of internal gravity waves by tidal flow over topography is an important oceanic process that redistributes tidal energy in the ocean. Internal waves reflect from boundaries, creating harmonics and mixing. We use laboratory experiments and two-dimensional numerical simulations of the Navier–Stokes equations to determine the value of the topographic slope that gives the most intens...

here the box at the top right-hand corner of the article or click Receive free email alerts when new articles cite this article-sign up in Internal gravity waves are generated in a stratified fluid by arbitrary forced oscillations of a horizontal disc. The wave fields are calculated in both the time domain and the frequency domain. In the time domain, an initial-value problem is solved using La...
متن کاملResonant generation of internal waves on a model continental slope.
We study internal wave generation in a laboratory model of oscillating tidal flow on a continental margin. Waves are found to be generated only in a near-critical region where the slope of the bottom topography matches that of internal waves. Fluid motion with a velocity an order of magnitude larger than that of the forcing occurs within a thin boundary layer above the bottom surface. The reson...
متن کاملThe Generation of Internal Waves by Explosive Volcanic Eruptions
Recent observations have shown that explosive volcanic eruptions can generate low frequency surface pressure signals that are observable with microbarographs, and can be interpreted as atmospheric internal waves (Baines & Sacks 2013). Some examples from the Caribbean island of Montserrat are shown in Figure 1. Suitably interpreted, it is possible that these observations may give information abo...
متن کاملGeneration of internal waves by sheared turbulence: experiments
A series of experiments is presented that model the generation of internal gravity waves in the ocean by the forcing of turbulent eddies in the surface mixed layer.The experimental setup consists of a shallowmixed upper layer and a deep continuously stratified lower layer. A source of turbulence is dragged through the upper layer. Internal waves can freely propagate in the lower layer. The inte...
