| 摘 要： | 根据2005年7月、2005年11月和2006年5月在长江口及其邻近海域进行的大范围水文调查资料,深入分析该海域余流的平面分布,垂直变化,大、小潮变化,季节变化等特征。结果表明,所测区域影响余流的因素很多,有底形、斜压、径流量、风应力、底摩擦、台湾暖流、浙江沿岸流、江苏沿岸流以及各因素间的相互作用。

| Abstract: | Based on the hydrographic data observed in the Changjiang River estuary and adjacent sea areas in July and November,2005 and May,2006,the horizontal distributions,vertical variations,difference between currents during spring and neap tides and seasonal variations in residual current in the sea area are analyzed.It is shown from the analysis results that the factors affecting the residual current in the sea area include bottom topography,baroclinity,river runoff amount,wind stress,bottom friction,Taiwan Warm Current,Zhejiang coastal current,Jiangsu coastal current and interaction between different affecting factors. |
