Did an El Niño event occur during the winter of 2015?
By December 2015*, however, disruptions in temperature, rainfall, and surface air pressure across the tropical Pacific were on par with two of the strongest El Niños in the historical record: 1982 and 1997.

Recent Central Pacific El Niños happened in 1986–87, 1991–92, 1994–95, 2002–03, 2004–05 and 2009–10. Furthermore, there were “Modoki” events in 1957–59, 1963–64, 1965–66, 1968–70, 1977–78 and 1979–80. Some sources say that the El Niños of 2006-07 and 2014-16 were also Central Pacific El Niños.

What is climate condition occurs during El Nino?
El Niño causes the Pacific jet stream to move south and spread further east. During winter, this leads to wetter conditions than usual in the Southern U.S. and warmer and drier conditions in the North. El Niño also has a strong effect on marine life off the Pacific coast.
What causes El Nino phenomenon?
Sea Surface Height. Sea level is naturally higher in the western Pacific; in fact,it is normally about 40 to 50 centimeters (15-20 inches) higher near Indonesia than off of
What causes El Nino event?
What causes an El Niño? An El Niño occurs when sea surface temperatures in the central and eastern tropical Pacific Ocean become substantially warmer than average, and this causes a shift in atmospheric circulation. Typically, the equatorial trade winds blow from east to west across the Pacific Ocean. El Niño events are associated with a weakening, or even reversal, of the prevailing trade
