Abstract

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.
