南极锋是指南半球高纬度的寒冷的南极气团与相对暖的中纬度气团之间的交界面,它是一种大范围的锋,锋上有波动产生。 在南半球,极地海洋气团与南极气团交绥形成南极锋。南极锋以北至副热带海区为亚南极海区,南极锋以南的海区为南极海区。南极锋以南及接近60°N以北的海域,形成辐散带,冷而重的海水上升至表层。
随着海洋变暖,一种被称为南极极锋的水体正被逐步推向南方;南极极锋是一种富含营养的海洋向上运动,它支持着大量海洋生物的生存。
As the ocean warms, a body of water called the Antarctic Polar Front—an upward movement of nutrient-rich sea that supports a huge abundance of marine life—is being pushed further south.
随着海洋变暖,一个被称为南极极锋的水体——一个支持大量海洋生物生存的营养丰富的海水上升运动——正被进一步推向南方。
As the ocean warms, a body of water called the Antarctic Polar Front—an upward movement of the nutrient-rich sea that supports a huge abundance of marine life—is being pushed further south.
