【摘要】 南海东北部是黑潮的动力、热力影响最为显著的海域.反气旋流套是黑潮入侵的主要形式,其水平最大位置在19°-22°N,117°-121°E之间,占据南海东北部海域约一半面积.在它西北部边缘,有东沙群岛绕岛反气旋涡和冬季逆风流.逆风流主流轴西从115°E起,东到台湾浅滩东面120°E止,北从大陆架边缘22°N起,南界到21°N,即大约1 500 m的陆坡边缘处止.其方向向东略偏北.在流套入口的南缘、巴布延群岛西侧有一个气旋涡,中心位置在19°N,120°30°E附近,空间尺度约为200km.此外,从黑潮流套(春、夏季)或从吕宋海峡(冬、秋季)直接分出一股黑潮水向西偏南流动,进入南海中部.冬季,19°N以北海域上层主要受黑潮水控制;春、夏、秋三季,黑潮水的入侵主要在200 m以下深层.更多还原

【Abstract】 Kuroshio entering the South China Sea (SCS) through the Luzon Strait has considerable impacts on the circulation, especially that in the northeastern SCS. This incursion forms an apparently anticyclonic loop current west of the Luzon Strait. The maximum extension is between 19°-22°N and 117°-121°E. The Winter Upwind Current (WUC, also known as the South China Sea Warm Current), is near northwest edge of loop current and its extension is between 21°-22°N and 115°-120°E. There are two mesoscale gyres, anticyclonic gyre around the Xisha Archipelago and cyclonis gyre west of Babuyan Archipelago. The Kuroshio has Zhongsha Branch. Its influences are mostly found in the upper mixed layer in winter north of 19°N and at deep levels from spring to autumn.更多还原
