摘要

摘要: 基于ROMS模式构建了模拟区域为（15.52°S-7.13°N，110.39°~134.15°E）水平分辨率为2’的潮波数值模式，分别模拟了印尼海域M₂、S₂、K₁、O₁四个主要分潮。模拟结果与29个卫星高度计交叠点上的调和常数进行比较，符合较好。M₂分潮的振幅均方根差为3.4 cm，迟角均方根差为5.9°；S₂分潮的振幅均方根差为1.7 cm，迟角均方根差为6.3°；K₁分潮振幅均方根差为1.1 cm，迟角均方根差为5.8°；O₁分潮振幅均方根差为1.2 cm，迟角均方根差为4.4°。M₂、S₂、K₁、O₁分潮向量均方根差分别为3.8 cm、2.4 cm、1.9 cm和1.3 cm，模拟结果的相对偏差在10%左右。根据计算结果分析了印尼海域的潮汐特征及潮能传播规律，结果显示：爪哇海以外的印尼海域主要为不规则半日潮区；全日潮潮能主要由太平洋传入印尼海域，而半日潮潮能则是从印度洋传入印尼海域。

Abstract: Based on the ROMS model, the high resolution tidal model for principal tidal constituents M₂, S₂, K₁ and O₁ in the Indonesias Sea (15.52°S~7.13°N,110.39°~134.15°E) is established. The model results are compared with observations at 29 TOPEX/Poseidon (T/P) crossover points, showing satisfactory agreement. The root-mean-square (RMS) deviations in amplitude and phase-lag are respectively 3.4 cm and 5.9° for M₂, 1.7 cm and 6.3° for S₂, 1.1 cm and 5.8° for K₁ and 1.2 cm and 4.4° for O₁. The vector RMS deviations for M₂, S₂, K₁ and O₁ are 3.8 cm, 2.4 cm, 1.9 cm and 1.3 cm respectively. The relative deviation of numerical results is about 10%. Based on the numerical results, the tidal characteristics and tidal energy flux are analyzed. Except for the Java Sea, the Indonesian seas are mainly irregular semidiurnal tide areas. The diurnal tidal energy propagates mainly from the Pacific Ocean to the Indonesian seas, however the semidiurnal tidal energy propagates from the Indian Ocean to the Indonesian seas.
