- Abstract
This paper analyzes the surface current characteristics along the coast of the Chinese mainland in autumn and winter by the trajectories of coastal drifters and remote sensing data. The results show the following: (1) During autumn and winter 2018, the paths of drifters were consistent with that of the Zhe-Min Coastal Water, while the Zhe-Min Coastal Water had a branch intruding the coast of Taiwan Island. (2) When the northeast monsoon weakened or changed direction in a short period, the Zhe-Min Coastal Water showed a reverse flow. (3) In the northeastern South China Sea, the drifter path meandered due to a dipole’s influence. (4) Around the frontal area near the Taiwan Bank, the paths of drifters showed a 12.4-h periodic variation, which was mainly controlled by the tidal current. These findings show that the coastal drifter is a useful tool to observe surface currents.
