摘要
孤立子内波是由内潮在特殊地形条件下所激发的存在于密度跃层中的大振幅波动。而在其传播过程中产生的扰动可导致海面海水强烈辐聚和突发性的强流 (波致流 ) ,对海洋工程、石油钻井平台和海底石油管道会造成严重的威胁。介绍了国际上研究海洋中孤立子内波的动态 ;描述了南海北部存在的孤立子内波现象 ,讨论了目前南海孤立子内波研究中存在的一些问题 ,进而提出了今后开展进一步研究的思路。
Internal solition is the large amplitude wave existing in the pycnocline induced by internal tide in the condition of special bottom topography. During the propagation process of internal solition,the induced disturbance can bring about strong convergence of sea surface water and sudden strong current(wave induced current),which can cause severe threat to the ocean engineering, oil drilling platform and sea bottom oil pipeline.The dynamic state of the international study on oceanic internal soliton is introduced,the internal solition phenomena existing in the northern South China Sea(SCS) is described,some problems about internal solition study now in SCS are discussed,and the study thought is put forward.
