What kind of currents bring warm air to land?
Zinaida [17]

Answer: A warm current is just the reverse. A warm current is moving away from the Equator toward the poles. The water in a warm current is warmer than the surrounding water.

Explanation: The surface water temperature varies considerably between the Equator and the poles. As the ocean water is distributed across the Earth's surface by drifts and currents (see the infrared satellite photo of the warm Gulf Stream moving north along the east coast of Florida), warm water from the lower latitudes is moved into the higher latitudes and cold water is moved Equatorward. If you will remember, we noted in the section on Latitude that this redistribution of heat by ocean water is one of the major ways excess energy is moved poleward (and cold water is moved Equatorward).

I hope this helps, good luck
