TLDR
In this article, the authors presented evidence for baroclinic tide origin of internal solitary waves (ISWs) in the northeastern South China Sea, based on 116 internal wave packets observed in satellite images from 1995 to 2001.Abstract:
[1] Evidence for baroclinic tide origin of internal solitary waves (ISWs) in the northeastern South China Sea is presented, based on 116 internal wave packets observed in satellite images from 1995 to 2001. These wave packets can be divided into two types, a single-wave ISW packet containing only one ISW with/without an oscillating tail, and a multiple-wave ISW packet composed of a group of rank-ordered ISWs. All of the 22 single-wave ISW packets occur in the deep water zone. It is suggested that the ISWs, instead of being generated by the lee-wave mechanism, are developed by nonlinear steepening of the baroclinic tides, which are produced by the strong tidal currents flowing over a ridge in Luzon Strait. This suggestion is verified by an ERS-2 SAR image, which records such an evolution process from a baroclinic tide to a single ISW in its spatial domain.read more

Deepwater overflow through Luzon Strait
TL;DR: In this article, the authors examined water property distributions in the deep South China Sea and adjoining Pacific Ocean using all available hydrographic data and revealed that below about 1500 m there is a persistent baroclinic pressure gradient driving flow from the Pacific into the south China Sea through Luzon Strait.

TL;DR: In this paper, 14 nonlinear internal waves are detected as they transit a synchronous array of 10 moorings spanning the waves' generation site at Luzon Strait, through the deep basin, and onto the upper continental slope 560 km to the west.

Prototypical solitons in the South China Sea
TL;DR: In this paper, the authors report on the evolution of an energetic packet as it propagated through the deep central basin of the South China Sea (SCS) toward the western slope and shelf, with amplitudes estimated at 170 m, half widths of 3 km, and phase speeds of 2.9 ± 0.1 m/s.

Statistical and dynamical analyses of generation mechanisms of solitary internal waves in the northern South China Sea
TL;DR: In this article, the effects of thermocline shoaling on the ocean internal wave (IW) generation in the north South China Sea (NSCS) were analyzed using seven years of satellite synthetic aperture radar (SAR) images from 1995 to 2001.
