摘要
海洋内孤立波是一种特殊的内波,它能够长距离的传播而保持波形的基本不变。世界上很多海域都观测到了内孤立波的存在,我国南海也是内孤立波频发的典型海区。本文介绍了内孤立波的生成机制、南海内孤立波的研究现状并探讨了南海内波的源、最后介绍研究内孤立波所用的传播模型,认为建立水平二维的内孤立波传播模型具有重要的意义。
Internal solitary waves are special internal waves which can propagate for a long distance while maintaining their wave forms. They exist in many oceans of the world including the South China Sea. This review pays attention mainly to the formation mechanisms of internal solitary waves and introduces the present state of research on solitary waves in the South China Sea. Finally we introduce the numerical models of internal solitary waves utilized at present. It is significant to establish a two-dlmensional numerical model to describe the evolution of internal solitary waves.
