根据南黄海江苏岸外辐射沙脊群潮流水道中16个站位的实测水文数据,利用潮流准调和分析方法和潮汐余流计算方法,对各个水道中的各测站的潮汐余流进行分析,计算得出了江苏辐射沙洲海域各潮汐水道对应的潮汐余流的数值结果.分析表明,辐射沙洲海域的潮汐余流的量值较大,外海开阔海域的潮余流量值较小;整个辐射沙洲区域有一顺时针方向的半封闭的潮余环流.“,”Successive measurements of tidal current were carried out at 16 stations in the radial sand ridge area of the South Yellow Sea off the Jiangsu coast.Using the methods of harmonic tidal analysis and tidal-induced current calculation,we calculated the tidal-induced residual current at every observation station.The results indicated that the tidal-induced residual currents are quite big in the radial sand ridge area,but rather small in the distant area offshore.There is a semi-closed tidal current moving in a clockwise direction in the radial sand area.
