阿拉伯海--将阿拉伯半岛与印度次大陆隔开的洋盆--上空的季风遵循季节性周期，在夏季和冬季一年两次逆转方向。西南(夏季)季风通常集中在阿拉伯海中部上空的急流中，而不是在辽阔的海洋上传播。有证据表明，风应力的变化迫使急流以西的海洋大量上升，而向东的上升流甚至下降流较弱。这种上升流为真光层提供营养物质，提高生物生产力。
Monsoons over the Arabian Sea—the oceanic basin that separates the Arabian peninsula from the Indian subcontinent—follow seasonal cycles, reversing directions twice a year, in summer and winter. Rather than spreading across the expanse of the sea, the southwest (summer) monsoon is often concentrated into a jet over the central Arabian Sea. Evidence suggests that variations in wind stress force substantial upwelling in the ocean to the west of the jet, and weaker upwelling or even downwelling to the east. This upwelling provides nutrients to the euphotic zone and enhances biological productivity.
