New progress has been made in the study of the influence of the circulation of the northern South China Sea on the propagation of internal solitary waves

Recently, Cai Shuqun's research team at the State Key Laboratory of Tropical Marine Environment, South China Sea Institute of Oceanology, Chinese Academy of Sciences has made new progress in the study of the influence of internal solitary wave propagation in the northern South China Sea circulation

Figure 1 Schematic diagram of solitary wave distribution characteristics and typical circulation structure in the deep sea basin of the northern South China Sea (the broken line box indicates the internal solitary waves in this area as the research object) 

Explores the researchers used a numerical model nonlinear refraction 1993-2015 years, 20 years in northern South China Sea, western boundary current and the Kuroshio intrusion in three different flow paths (Figure 1a of Looping , Leaping and Leaking ) deep basins spread across northern South China Sea The influence law of internal solitary wave amplitude and phase velocity

This study clarified the modulation law of the circulation and evolution of internal solitary waves in the northern South China Sea, and provided a theoretical basis for the accurate numerical simulation and prediction of internal solitary waves in the South China Sea in the future

The research consists of the Chinese Academy of Sciences Frontier Science Key Research Project, the National Natural Science Foundation of China, the Southern Ocean Science and Engineering Guangdong Laboratory (Guangzhou) Talent Project, the Independent Deployment Project of the Nanhai Eco-Environmental Engineering Innovation Research Institute of the Chinese Academy of Sciences, and the "Guangdong Special Support Program" The “Young Top Talent Project” and the “South China Sea Rising Star” project of the South China Sea Institute of Oceanology, Chinese Academy of Sciences, etc.
