Effect of internal solitary waves on mine detection in the western Philippine Sea east of Taiwan
… themistors attached from July 28-August 7, 2005. Internal waves and internal solitons were identifed during the empirical orthogonal function analysis. Without the IW and IS, the power spectra, structure functions, and singular measures (respresenting the intemittency) of the temprature field …

Modeling flow encountering abrupt topography using hybridizable discontinuous Galerkin projection methods
… projection methods, including the formation of internal wave beams over a shallow but abrupt seamount, the generation of internal solitary waves from stratified oscillatory flow over steep topography, and the circulation of bottom gravity currents down a slope. Additionally, we investigate the …

Dynamics Of Internal Solitary Wave And Bottom Boundary Interaction
The breaking of internal solitary waves (ISWs) of depression shoaling upon a uniformly sloping boundary in a smoothed two-layer density field was investigated using high-resolution two-dimensional simulations. The simulations were performed for a wide range of boundary slopes S∈[0.01,0.3] and wave …

The refraction, shoaling and structure of non-linear internal waves at a continental shelf margin
Observations of internal waves near the Continental shelf-edge are generally ascribed to generation by oscillating tidal flow over the local bathymetry, in the presence of a stratified water column, giving rise to the internal tide. In this thesis observations are presented which demonstrate that …

A high-order hybrid flow solver for the simulation of nonlinear internal waves in long complex domains
The simulation of nonlinear internal waves (NLIWs) is a challenging task for several reasons. The inherent long width of NLIWs and their long propagation distances necessitate high-aspect-ratio, anisotropic and usually deformed (due to complex bathymetry) computational domains. Furthermore, the …

High-order Discontinuous Galerkin Methods and Deep Reinforcement Learning with Application to Multiscale Ocean Modeling
… dynamical regimes including linear gravity waves, internal solitary waves, and the formation of Rayleigh-Taylor instabilities in the mixed layer. Motivated by investigating local nonhydrostatic submesoscale dynamics using realistic ocean simulation data, we develop schemes to initialize and …
