The northeastern South China Sea (SCS) is affected by Kuroshio intrusion and monsoon, etc., the background shear currents are complicated, the eddies are active, and the seasonal variation of sea water vertical stratification is distinct, meanwhile, due to the effects of the complicated bottom topography in the Luzon Strait and strong tidal currents, the internal tides and internal solitary waves here are very active. However, in the previous studies on internal tides/solitary waves, few correlations with the background shear currents/eddies are considered. Therefore, it is difficult to reveal the generation, propagation and evolution rules of internal waves are difficult to be revealed. In this paper, we summarize the progress on the studies of meso-scale phenomena of shear currents, eddies and internal waves in the northeastern SCS and their interaction, and then propose some problems on future study of the effect of shear current field on the generation, propagation and evolution rules of internal waves in the northeastern South China Sea as well as the solution methods are proposed.
Key words： Internal tide; Internal solitary wave; Shear current; Eddy; South China Sea.
