南海北部上层海洋变化的定点观测分析

Variation of upper ocean in the northern South China Sea from mooring station observations

对南海季风试验（ＳＣＳＭＥＸ）加密观测期（ＩＯＰ）“实验３”号船在南海北部获得的ＣＴＤ温盐和声学多普勒流速剖面仪（ＡＤＣＰ）海流等观测资料进行分析，给出东沙群岛西南部大陆坡附近ＩＯＰ两个阶段定点观测的海洋分量部分结果．通过分析海水的动力、热力学结构，描述夏季风暴发、维持期间该测站上层海洋的变化，讨论近表面水的温度、盐度和海流对海面风场的响应。

CTD temperature, salinity and ADCP current data, which were observed by R/V Shiyan No. 3 during the South China Sea Monsoon Experiment (SCSMEX) intensive observational period (IOP), have been analyzed, showing some results of observations at a mooring station located in the vicinity of continental slope off in the south of Dongsha Islands. The dynamic and thermodynamic structures and their changes are analyzed to describe the upper ocean variation at the northern south China Sea area during the summer monsoon onset and maintaining periods. The response of near-surface water temperature, salinity and current to local sea surface winds are also discussed.
