This leads to a very slight cooling of the surface relative to the satellite record adjusted to surface variation levels. (climateaudit.org)
For example, scientists have found that El Niño and La Niña, the periodic warming and cooling of surface waters in the central and eastern tropical Pacific Ocean, are correlated with a higher probability of wet or dry conditions in different regions around the globe. (sciencedaily.com)
The climatic change at issue is known as the Atlantic Multidecadal Oscillation (AMO), a periodic cycle of warming and cooling of surface temperatures in the North Atlantic. (discovermagazine.com)
