综述了南海北方内孤立波及其动力学过程的研究现状。这种独特的波动现象直到十多年前才引起人们的兴趣，现在是波动力学领域的热门话题之一。本文总结了三种研究方法，即遥感图像、现场测量和数值模拟。总结了南海北方ISW从吕宋海峡（LS）起源到深盆形成、演化、在陆架坡折附近转化直至在陆架上消散的整个生命周期，并分析了ISW的演化特征。并举例说明不同的调查方法。总结了影响波浪生成过程的各种因素。LS中的正压潮汐、黑潮入侵、层结的时空变化以及LS中西脊的调制等因素都能显著改变波场，并得到了广泛的讨论。
The current research into internal solitary waves (ISWs) and the related dynamic processes in the northern South China Sea (SCS) are reviewed in this paper. This unique wave phenomenon did not draw much interest until about one decade ago, and is now one of the hot topics in the field of wave dynamics. Three methods of investigation are summarized in the paper, namely, remote sensing images, in situ measurements, and numerical simulations. Previous works have primarily been based on one or two of these methods and have provided great insights into such wave phenomena.The lifetime of an ISW in the northern SCS, from its origin in the Luzon Strait (LS), through to its formation and evolution in the deep basin, and its transformation near the shelf break, up until its dissipation on the continental shelf, is summarized, with the illustration of different investigation approaches. Various factors that can affect the wave generation processes are summed up as well. Such factors as are barotropic tides in the LS, Kuroshio intrusion, temporal and spatial variation of stratification, and the modulation of the western ridge in the LS can significantly alter the wave fields and are extensively discussed.
