摘要

Abstract

TOPEX/POSEIDON altimeter data from October 1992 to June 2002 are used to calculate the global barotropic M 2 tidal currents using long-term tidal harmonic analysis. The tides calculated agree well with ADCP data obtained from the South China Sea (SCS). The maximum tide velocities along the semi-major axis and semi-minor axis can be computed from the tidal ellipse. The global distribution of M 2 internal tide vertical energy flux from the sea bottom is calculated based on a linear internal wave generation model. The global vertical energy flux of M 2 internal tide is 0.96 TW

with 0.36 TW in the Pacific

0.31 TW in the Atlantic and 0.29 TW in the Indian Ocean

obtained in this study. The total horizontal energy flux of M 2 internal tide radiating into the open ocean from the lateral boundaries is 0.13 TW

with 0.06 TW in the Pacific

0.04TW in the Atlantic

and 0.03 TW in the Indian Ocean. The result shows that the principal lunar semi-diurnal tide M 2 provides enough energy to maintain the large-scale thermohaline circulation of the ocean.
