摘 要: | With the development of satellite altimetry technology, the resolution of sea-level anomaly(SLA) datasets is constantly improving. Current spatial resolution levels can reach a grid size of (1/4)°×(1/4)°, with daily measurements that span from 1993 to 2018, allowing for the precise identification and tracking of individual eddies. In the current study, in addition to the internal circulation and migration of eddies, a new aspect in eddy kinematics is revealed and investigated for the first time:...
