【摘要】 冬季,在南海西南部海域存在一个海盆尺度的气旋环流.夏季,约在12°N以南海域,存在一个范围广大的反气旋式环流.南北距离约为1 000 km,东西距离约为700 km,最大流速位于这个环流西部和北部.在总环流背景下出现形形色色中小尺度涡旋.冬季最明显的有南沙气旋涡和巴拉望气旋涡.夏季则有西陆架区反气旋涡、金兰湾反气旋涡、民都洛反气旋涡、巴拉望反气旋涡、万安滩南反气旋涡和南安礁反气旋涡等.更多还原

【Abstract】 The winter regime of circulation is a cyclone. It forms in October and enhances its speeds from January to March. Under the surface, the speeds along NE fringe of the circulation are weakened and strengthened along the Borneo. The summer regime of circulation is ticyclone. It occupies the area south of 12°N about 1 000 km in N - S direction and 700 km in E - W direction. Jinlan Current is northern edge of the anticyclonic circulation. There are maximum speeds in the west and north parts of the circulation. Under 200 m, the circulation scale is remarkably reduced. There are many mesoscale gyres in this region. They are Nansha cyclonic gyre and Balawan cyclonic gyre in winter. They are anticyclonic gyre in the west continental shelf and anticyclonic gyre east of Jinlan Bay and Mindoro anticyclonic gyre and Balawan anticyclonic gyre and Nan’an Reef anticyclonic gyre in summer.更多还原
