Nonhydrostatic Numerical Investigations of Oscillating Flow over Sills: Generation of Internal Tides and Solitary Waves

Abstract

The goal of this project is to identify processes relevant to the finite-amplitude, internal solitary waves observed in the region from the Luzon Strait to the Chinese continental shelf in support of ONR's Nonlinear Internal Waves Initiative (NLIWI). A nonhydrostatic numerical model was adapted to study these waves. Wave generation by a ridge, propagation in the deep basin, and reflection and diffraction by an island were successfully simulated by the numerical model. Parametric dependence of wave characteristics on stratification, ridge height, and bottom topography was studied.
