Abstract：The mesoscale eddies in the South China Sea are extracted and analyzed by geometric velocity method based on sea surface temperature data and sea level anomaly data. The results show that both sea surface temperature and sea level anomaly data can extract eddies; the two extraction capacities are basically the same but there are differences: sea surface temperature data can extract small scale eddies but show instability when tracking eddies, while sea level anomaly data cannot detect small scale eddies but shows stability when tracking eddies. In addition, the temporal and spatial distribution of these eddies extracted by the two data are consistent.
