Description
This study investigated impacts of internal tdies on oceanic flows and developed a tide prediction system with considering internal tides. Numerical simulations employing SUNTANS show that large internal tide flux in the northern area of Izu-Ogasawara Ridge. The baroclinic kinetic energy excited by internal tides explains 59% of the total kinetic energy in the study domain. This implies that internal tides play an important role in oceanic flows. Internal tides cause complicated flow structures and they significantly influence sea surface flows. The tide flow prediction system has been developed using database obtained by the numerical model. The system has released to provide forecasting figures of tidal flows through the web site.
