摘要
南海东北部受黑潮入侵、季风等动力因素的影响,背景剪切流场复杂,涡旋众多,水体垂向层结季节性变化明显,同时又因吕宋海峡的复杂底地形和强潮流的影响,内潮、内孤立波现象显著。但是,以往关于内潮、内孤立波的研究很少考虑到背景剪切流场和涡旋对其影响,因而难以揭示内波的生成、传播和演变规律。主要概述了南海东北部的剪切流、涡旋和内波等多种中尺度物理现象及其之间的相互作用的研究进展,进而提出未来关于南海东北部剪切流场对内波生成、传播和演变影响研究中的一些问题和研究思路。
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.
