Large Amplitude Breaking Internal Solitary Waves: Their Origin and Dynamics.

摘要

The long-term goal is to determine the mechanisms of generation, propagation, dissipation, mixing and decay of large amplitude internal waves formed by tidal flow past topography. Our objectives are to use both acoustic remote sensing and in situ profile observations of large amplitude internal waves, together with highly resolved numerical simulation, so as to develop a predictive understanding of their behavior, with application to their generation by flow past topography, their contribution to mass and momentum transport, mixing, modulation of near surface bubble clouds and related properties. A further objective is to use the numerical simulation to test hypotheses related to observed convective overturning and shear instability induced by the waves under different conditions of stratification and shear and to estimate the mixing and dissipation resulting from these processes.
