Abstract
Abstract : Nonlinear internal solitary waves generated within Luzon Strait move westward across the northern South China Sea, refract around Dongsha Atoll, and dissipate on the Chinese continental shelf after a journey of over 500 km lasting more than four days. In the last 10 years a great deal of observational, theoretical, and modeling effort has been directed toward understanding and predicting these solitary waves and their effects on the oceanography of the northern South China Sea. This paper reviews a variety of modeling approaches (two- and three-dimensional, kinematic, hydrostatic, and nonhydrostatic) that have been employed to gain insight into the generation mechanisms and physics of the South China's Sea's nonlinear solitary waves with the goal of predicting wave characteristics such as phase speed, amplitude, and arrival time.

This paper reviews a variety of modeling approaches that have been employed to gain insight dimensional tide modeling that was into the generation mechanisms and physics of the South China Sea’s nonlinear integrated into the Hawaiian Ocean solitary waves with the goal of predicting wave characteristics such as phase speed, Mixing Experiment
In recent years, modeling and field edge in its goal of predicting, to within tidal currents with magnitudes reaching programs have become ever more tightly one hour or less, the arrival time of a 100 cm s–1 during spring tides flow integrated as modeling capabilities have phenomenon with nearly east-west across the ridge topog- continued to improve
The westward-propagating tides steepen and evolve into large-amplitude nonlinear internal waves that can be identified in satellite imagery and in situ observations (Figure 2 and Farmer et al, 2011, in this issue)

Comparison between predicted nonlinear wave positions in the South China Sea and those observed by Moderate Resolution Imaging Spectroradiometer (MODIS) April 22 at 5:05 pm. The MODIS image (left) shows sun glint, whereas the simulation (right) indicates deviation of the 200 m isotherm induced by the internal tide and nonlinear internal waves. Nonlinear internal solitary waves generated within Luzon Strait move tides within a few wavelengths of their westward across the northern South China Sea, refract around Dongsha Atoll, and generation site are uniquely suited to dissipate on the Chinese continental shelf after a journey of over 500 km lasting simulation because the basic physics is more than four days. This paper reviews a variety of modeling approaches (two- and three-dimensional, this combined approach is the threekinematic, hydrostatic, and nonhydrostatic) that have been employed to gain insight dimensional tide modeling that was into the generation mechanisms and physics of the South China Sea’s nonlinear integrated into the Hawaiian Ocean solitary waves with the goal of predicting wave characteristics such as phase speed, Mixing Experiment
