| 中文摘要 | The Conductivity-Temperature-Depth (CTD) and acoustic Doppler current profiler (ADCP) measurements along 18 degrees N off the western Luzon in the South China Sea (SCS), collected during a cruise from August 12-14,2012, were used to explore the vertical structure of an anticyclonic eddy (AE) during the observational period. Further, the French Archiving, Validation and Interpretation of Satellite Oceanographic data (AVISO) sea level anomaly (SLA) and corresponding anomalous surface geostrophic velocity were used to study the temporal evolution of the AE. The vertical structure of the AE along 18 degrees N in August 2012 showed a trough located near 117.5 degrees E. The AE extended vertically downward and its distinct feature was identifiable to 200 m depth. Seasonal variations of SIA indicate that the AE lasted for 5 months (June to early November), going through the growth and nearly stationary period from mid-June to late August and then propagating westward along 18 degrees N with varying phase speeds and shapes to the continental slope off the southeastern Hainan Island during late September to November. Furthermore, T-S characteristics suggest that the AE was generated off the western Luzon. Interannual variations of the summer (July-September) SLA presented by Empirical Orthogonal Function analysis, indicates that the local circulation was enhanced by the anomalous anticyclonic eddy along 18 degrees N in the years of 2008, 2010, 2012 and 2013 during the period from1993 to 2014.
