Definition and Explanation
A cold circumpolar current is an oceanic current characterized by cold water temperatures that flows continuously in a circular path around the polar regions. The most well-known is the Antarctic Circumpolar Current (ACC), which encircles Antarctica and connects the Atlantic, Pacific, and Indian Oceans. The current is driven by strong westerly winds and differences in water density, known as thermohaline circulation.
