西澳洋流

環繞澳洲大陸的洋流。西澳洋流與利文洋流英语Leeuwin Current位置重疊,但程反方向流動。

西澳洋流(英語:West Australian CurrentWestern Australian Current),是位於南冰洋南印度洋表面的寒流,具季節性,於冬季較弱,夏季較強,而且受當地風勢影響[1][2][3]

位置范围

[编辑]

西澳寒流位于澳大利亚西岸,南印度洋东岸。

成因

[编辑]

因为南半球西风漂流遇澳大利亚大陆阻挡而较高纬洋面升高,同时印度洋的南赤道暖流抽走海水导致较低纬海区洋面降低,从而导致洋流从较高纬流至较低纬形成寒流,是一种补偿流。 同时受离岸的信风作用,表层海水被带走,深层较冷的海水涌升,亦是垂直方向的补偿流、寒流[4]
