摘    要:东山湾是福建重要的天然良港.根据2008年8月的3个潮次11个测站实测潮流资料结合历史调查资料分析东山湾的潮流性质、运动形式、涨落潮流特性、余流等特征.结果表明,东山湾主要属于往复式的规则半日潮流,潮流作用较强,其口门处和湾内水道上的实测最大流速一般大于100cm/s.持续时间较长的风对东山湾的余流较大的影响,大潮期间湾内存在明显的反时针的水平余环流系统.

关 键 词:物理海洋学  东山湾  潮流  余流

Abstract:Dongshan Bay is an excellent natural harbour in Fujian.The data obtained from 3 investigations in August 2008 with 11 observatories located in Dongshan Bay are used to analyze the type and the motion form of tidal current,the characteristics of flood current,ebb current and the residual current in Dongshan bay combining with historical survey observations.The results show that the tidal property in Dongshan Bay belongs to regular semidiurnal tide.The action of tide current is strong and the flow velocity is currently more than 100cm/s in the bay mouth area and the channel.The residual current is obviously influenced by the wind of relatively long duration and the horizontal residual current is counterclockwise in the bay during the spring tide.
Keywords:physical oceanography  Dongshan Bay  tidal current  residual current
