摘　　要：根据2006年8月—2007年12月期间在浙闽海域进行的连续观测长达40天的逐季海流资料,深入分析该海域余流的分布特征及季节变化规律,为浙闽海域的物质输运做出铺垫。研究结果表明:浙闽海域南侧(以28°N为界)余流值大于北侧。近岸区域余流受长江冲淡水、浙闽沿岸流控制,余流分布季节特征明显;外海余流受台湾暖流控制,余流流向终年指向E-NE。The characteristics and seasonal variations of residual current of Zhejiang-Fujian water were systematically analyzed in this paper based on the surveys of four seasons from August 2006 to December 2007,which can build foundation for long-term mass transportation along Zhejiang-Fujian water.The results show that the residual current of south Zhejiang-Fujian sea is stronger than that of north Zhejiang-Fujian sea.The seasonal variations of residual current along the coast are obviously dominated by the Yangtze diluted water and the Zhejiang-Fujian coastal current;however,the directions of residual current far off the coast point to the north-northeast all the year,which is influenced by Taiwan warm current.
