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...
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...

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 کاملGeneration of Internal Tides and Internal Solitary Waves on the Continental Shelf
There are two principal objectives. The first is to continue the development of amplitude evolution equations of the Korteweg-de Vries type with a main focus on topographic effects, and on the associated effects of refraction and friction. The second is to undertake a major re-examination of the generation process, using a combination of theoretical and numerical analyses, and emphasising the d...
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...
