El Niño By Diana Hayden and Jon Mittelstadt is a phenomenon in the equatorial Pacific Ocean characterized by a positive sea surface temperature departure from normal averaged over three months. There is also a shift in convection in the western Pacific further east than average.

17 Αυγ 2011 · In 2010, the El Niño-Southern Oscillation ("ENSO," for short) climate pattern swung first through its warm phase and then its cool phase, with significant influences on seasonal climate around the globe.
[1] The latest El Niño event in 2009 –2010, which is classified as warm pool El Niño, holds a unique ground in that it marks the strongest warming signal in the central Pacific but rapidly decays to strong La Niña.
15 Δεκ 2016 · El Niño started from July 2009 and the condition prevailed up to April 2010. Then, two months later, La Niña started in July 2010 and prevailed up to April 2011. As per the NOAA's criteria, 2009 is considered as moderate El Niño year and 2010 as strong La Niña year.
1 Δεκ 2009 · An El Niño event, which started in June 2009, is well established across the tropical Pacific. El Niño conditions are very likely to continue at least through the remainder of 2009 and into the first quarter of 2010. Some climate patterns typical of El Niño have been observed over the last several months. The expected
Since March, 2009, SOI has oscillated near its long–term monthly values, which is common during ENSO–neutral conditions, but may also occur as an El Niño or La Niña becomes established. Typically, prolonged periods of negative SOI values correspond to warmer–than–normal sea surface temperatures and El Niño episodes, while positive ...
