This happened this winter, moving warm air northwards over the Arctic, preventing sea ice forming as extensively as normal.
Usually, equatorial currents and trade winds move warm waters westwards, however, with El Nino, currents across the Pacific switch, sending warm waters eastwards.
Many ocean currents are driven by surface-level winds; they move warm water from the tropics to the poles and cold water from the poles toward the tropics.
On hot summer days, he said, prison officials restrict outside activity, provide frequent water breaks, allow additional showers, permit inmates to wear shorts and increase airflow by using blowers normally used to move warm air in the winter.
Instead of air being forced through overhead ducts, an energy-saving displacement ventilation system moves warm and cool air through an air plenum and multiple diffusers in elevated floors.
If, as Lovelock forecasts, the Arctic ice melts as a consequence of global warming, the Gulf Stream - the flow that moves warm water towards northern Europe from the Caribbean - will cease.
This 90-minute show is an absolute delight: moving, warm, generous and sparkling with the absurdly hilarious interjections of a woman who has both Tourette syndrome and an extremely Pythonesque sense of humour.
East winds moving over this warm water move warm air from over the Gulf Stream inland, helping to keep temperatures milder across the state than elsewhere across the Southeast during the winter.
Hurricanes help to maintain the global heat balance by moving warm, moist tropical air to the mid-latitudes and polar regions.
The Gulf Steam is one component of the AMOC, which moves warm water northward in the upper levels of the Atlantic.
