| Abstract: |
| POM97,an oceanic model,has been used for the first time to the numerical study on the tidal waves of the sea regions around Taiwan.In this paper,we have got the result that the semidiurnal tidal waves of these area mainly are the co-operating tides which come from the south of 23°N of the western Pacific.Those semidiurnal tidal waves affecting the Taiwan Straits come respectively from the south and the north entrance of the channel,and the north tidal wave is stronger than the south one.The strongest tidal field is the area from the Meizhou Bay to the Xinhua Bay along the coast of Fujian Province,where the biggest amplitude of the M2 partial tide can reach 240 cm.The strongest tidal cur rent fields lie in the Penghu watercourse,where the maximum velocity of the M2 partial tide can arrive at 196 m/s.In the horizontal structure of the tidal currents,we have found that there is a stream dot in the north of the channel,besides,there still exist four new ones.As for the vertical structure,it mainly is biassed to the right at the surface,and to the left near the bottom layer. |
