The article examines the characteristics of tidal and residual currents in the seas near Zhejiang. Researchers analyzed field data to understand the movement patterns of these currents. They identified the types of tidal currents and their distribution in summer and winter. The study also determined the maximum current velocities and the shape of tidal current ellipses. Overall, the research provides valuable insights into the behavior of tidal and residual currents in the coastal zone of Zhejiang Province.
