Who is Meteorologist Jeff Masters, the Man Behind the Snowpocalypse, Global Warming "connection?"
This is what I think is happening and may explain just what an El Nino is. A normal El Nino does not mean net Global Warming occurred. It can only indicate that if undersea volcanic activity or a massive solar flare had occurred. Everything with regards to the atmosphere is pressure related. Pressure determines the wind direction and speed. Strong cold winds cool ocean waters. Reference Western Floridian coastal water early January 2010. Strong warm air winds can warm the water. Reference waters near South Eastern South America right now. In normal times the trade winds move at a velocity which cools and evaporates sunlight warmed shallow water in the equatorial regions at what can be considered to be its normal rate. That energy generally stays within the tropics. When the trade winds are weak however, we get a warmer then normal body of water around the equator. Sunlight energy is not being cooled or evaporated as quickly due to slow winds. Some of that vapor energy however can be peeled off into the mid latitude temperate zones because winds are relatively stronger in those regions. Now when the trade winds are very strong the wind can cool the water at a rate greater then normal. The resulting water currents can be so strong that cold water deep upwelling can also occur along the upwind coastal regions. Again, is it the speed of the trade winds that determine everything in this relationship. No net warming or cooling occurs globally, but some minor long term flux differences are bound to occur between ocean and atmosphere heat contents.
