The tropical oceans have the greatest influence on land temperatures. The reason is that warmer tropical oceans result in lots of atmospheric convection from the   surface up to about 10-15km above the ocean: the troposphere. Changes in colder   ocean temperatures will not cause the kind of convection that penetrates up into   the troposphere.\\ In the tropics, once the warmer temperatures reach the troposphere they spread out and encircle the earth. In this way, the ocean surface temperature in just one part of the tropics can control the entire tropical atmosphere.\\
