碩士 / 國立中山大學 / 海洋環境及工程學系研究所 / 106 / Taiwan suffered several typhoons every single year. The change in atmospheric pressure and strong winds caused by typhoons have a great impact on the sea wave motion characteristics near Taiwan. Current would also influence the wave characteristics. It is therefore important to understand the effects by wave-current interactions. We applied a fully coupled wave-current model (SCHISM-WWM) that based on unstructured grids which is suitable for high-resolution coastal studies to calculate the phenomenon that may occur on the sea surface. To know the wave-current interactions that may occur in Nanwan bay, we use the wind field data from the Central Weather Bureau’s weather forecasts(WRF). The coupled model is shown to be able to capture the wave-current interactions in Nanwan bay. Our results shows that the wavelength becomes shorter in the opposing current and lead to the increasing of wave number. Wave height and wave steepness are also getting higher due to the changes of the wave number.
