The winter western boundary current of the South China Sea: physical structure and volume transport in December 1998

Third Institute of Oceanography, State Oceanic Administration, Xiamen 361005, China

摘要

摘要: 1998年12月航次是迄今为止冬季唯一一次覆盖了整个南海西边界海域的海洋调查。它全尺度地揭示了冬季南海迅疾而幅窄的西边界流的三维结构及其庞大的体积输运。该西边界流自香港外海直至巽他陆架沿大陆架外沿流动，其幅宽在100km左右，垂直尺度约400m。在中印半岛外海该海流达最强，其体积输运超过了20 Sv（1Sv=1×10⁶m³s^-1）。在其上游南海北部香港以西海域该海流偏弱，更往东则观测到一黑潮流套或其分离涡旋从吕宋海峡侵入，西边界流不复存在。该结果表明，观测期间南海冬季西边界流主要源自南海内部环流之注入，而非如以往表层漂流浮标所示来自吕宋海峡的黑潮“分支”。那可能只是一近表层现象，对南海冬季西边界流的总输运贡献偏小。论文并讨论了若干相关问题。

Abstract: The unique survey in December 1998 mapped the entire western boundary area of the South China Sea (SCS), which reveals the three-dimensional structure and huge volume transport of the swift and narrow winter western boundary current of the SCS (SCSwwbc) in full scale. The current is found to flow all the way from the shelf edge off Hong Kong to the Sunda Shelf with a width around 100 km and a vertical scale of about 400 m. It appears to be the strongest off the Indo-China Peninsula, where its volume transport reached over 20×10⁶ m³/s. The current is weaker upstream in the northern SCS to the west of Hong Kong. A Kuroshio loop or detached eddy intruded through the Luzon Strait is observed farther east where the SCSwwbc no more exists. The results suggest that during the survey the SCSwwbc was fed primarily by the interior recirculation of the SCS rather than by the “branching” of the Kuroshio from the Luzon Strait as indicated by surface drifters, which is likely a near-surface phenomenon and only contributes a minor part to the total transport of the SCSwwbc. Several topics related to the SCSwwbc are also discussed.
