Characters of tidal current dynamic in the Xiamen Bay
摘要
Abstract
On the bases of the observations from several short-term and long-term ocean stations in the Xiamen bay,the characteristics and the motion pattern of the tidal current,flood current,ebb current and residual current,the influence of the wind on the tidal current in the Xiamen bay are studied.The results show that:the reversing tidal current in the Xiamen Bay resulted a regular semidiurnal characteristic.The largest velocity of the tidal current is observed in the channel with a value higher than 100 cm/s.The residual current velocity is larger during the spring tidal than that during neap tidal,with a value smaller than 10cm/s on usual.In the vertical,the velocity of residual current has a little variation.Generally,the direction of the residual current shows an angle between the tidal current and point to the outside of the bay or opposite direction.Under the influence of strong wind(higher than 6 level) on the Beaufort,the shoaling effect of tidal wave is further enhanced,and the residual current velocity is reduced at station C5.When the southwest wind blows,the direction of the residual current at station C2 and C5 shows clockwise and anticlockwise deflection,respectively.The deflection angle is smaller in the deep water than in the sea surface.When the northeast wind blows,both of the two stations show a clockwise deflection,and the deflection angle changes little in the vertical.关键词
