在分析整理渤海、黄海区的海流观测资料时,我们发现海区内潮流运动方向的旋转是异常复杂而多变的。有的区域,潮流的旋转方向以反时针为主,有的区域则以顺时针为主;有的区域潮流的旋转方向比较稳定,有的区域则很不稳定。更令人感兴趣的是有的区域,即使在同一天的观测中,其不同层次的旋转方向可以彼此不同;而且,有的层次其流向还仅仅被局限某一定方位内进行摆动(见表一)。另据航海部门反映,他们在黄海、东海的长期航行表
When analyzing and analyzing the current observation data in the Bohai Sea and the Yellow Sea, we find that the rotation of the tidal current in the sea area is extremely complicated and changeable. In some regions, the direction of rotation is mainly counterclockwise, while in other regions clockwise is dominant. In some regions, the direction of rotation is relatively stable, while some regions are unstable. What is even more interesting is that some regions may rotate at different levels in different directions even in the same day of observation. Moreover, the flow of some levels may only be swung within a limited certain orientation (see Table 1 ). According to the navigation department to reflect their long-term navigation table in the Yellow Sea, East China Sea
