Via the National Oceanic and Atmospheric Administration, El Niño returns in July 2009

NOAA announced on July 9, 2009 that the climate phenomenon called El Niño has returned. The El Niño Southern Oscillation is characterized by low ocean surface winds along the Equatorial Pacific, generating warmer than average ocean temperatures. These warmer temperatures are visible in sea surface temperature anomaly data, such as is shown in this animation.
