What is a cold temperature current?

A cold temperature current is an ocean current that transports cold water away from polar regions. These currents are formed when cold, dense water sinks below the surface of the ocean and travels away from the poles. Cold temperature currents can have a significant impact on the climate of the regions they flow through, as they can bring cold air and cold water from the poles to warmer regions. Some of the most well-known cold temperature currents include the Humboldt Current, the Benguela Current, and the Canary Current.
