摘要

摘要: 内波沿着与水平面形成一定夹角的波射线进行传播.吕宋海峡生成的内波在传播过程中,其波射线在海面、海底及双海脊区域会发生反射,从而波射线可能会陷于双海脊之间,并在反射中逐步收敛到一个闭合的轨道,即内波吸引子.本文利用海洋环流模式MITgcm进行了两个三维非静压数值试验,来探讨吕宋海峡双海脊区域生成内波吸引子现象的可能性.两个数值试验的分辨率、初始场、驱动场等条件具有明显差异,但两者的输出结果都在20°N和21°N附近的一些断面上发现了斜压流形成的环形结构.这表明吕宋海峡具备生成内波吸引子的条件,并且温盐场、背景潮流等因素的小扰动不会影响到该现象的存在性.

Abstract: Internal waves propagate along wave beams that are inclined with respect to the horizontal plane. It is conjectured that the internal waves generated in the Luzon Strait may be confined between the double ridges in the strait and concentrate to a closed trajectory, the so-called internal wave attractor, due to the reflection of wave beams from the lateral boundaries, sea surface and bottom. This work carried out two experiments using a three dimensional non-hydrostatic general circulation model, MITgcm, to investigate the possibility that the ridges in the Luzon Strait allows for internal wave attractors. Baroclinic current in both of the experiments demonstrate the forming of ring-like patterns in some section around 20° and 21°N, indicating that the development of the internal wave attractors are allowed in the Luzon Strait. The different resolutions and initial conditions in the two experiments also reveal that the internal-wave-attractor phenomenon is robust in this region.
