| 摘 要： | 文章采用三维海洋模式MITgcm, 对印度尼西亚海(简称印尼海)内潮的生成和传播过程进行了研究。研究结果表明: 1)苏拉威西海和西北太平洋地区的内潮呈现明显的全日潮信号; 望加锡海峡、翁拜海峡、东北印度洋、帝汶海等站位的内潮呈现明显的半日潮信号; 2)印尼海区内潮的标准化振幅在苏拉威西海、望加锡海峡、翁拜海峡、马鲁古海、班达海、东北印度洋和西北太平洋地区均在温跃层附近达到最大, 约为20~40m; 在帝汶海地区在水深200m附近达到最大, 约为25~30m; 3)桑岭、斯兰海、翁拜海峡和帝汶海是主要的内潮生成区域, 内潮能通量达40kW·m-1; 4)苏禄海的内潮能量主要来自于局地正压潮的转化, 苏拉威西海和班达海的内潮能量则主要来自外部的传入。

| Abstract: | The generation and propagation of internal tides in the Indonesian Seas are investigated by using a three-dimensional ocean model of MITgcm. We find that diurnal tides prevail in the Sulawesi Sea and in the northwestern Pacific, whereas semi-diurnal tides are dominant in the Makassar Strait, Ombai Strait, Timor Sea, and northeastern Indian Ocean. The normalized amplitude of internal tides maximizes near the thermocline in the Sulawesi Sea, Makassar Strait, Ombai Strait, Maluku Sea, Banda Sea, northeastern Indian Ocean, and northwestern Pacific with values of about 20~40 m, whereas it maximizes near the depth of 200 m in the Timor Sea with a value of about 25~30 m. The Sangihe Sill, Seram Sea, Ombai Strait, and Timor Sea are the four major sites of internal tide generation, where the depth-integrated baroclinic energy flux reaches 40 kW·m-1. The internal tide energy in the Sulu Sea is mainly generated from the conversion of local barotropic tides, whereas that in the Sulawesi Sea and Banda Sea is from remotely generated internal tides. |
