El Niño is a natural climate event caused by the Southern Oscillation, popularly known as El Niño or also in meteorological circles as El Niño-Southern Oscillation or ENSO, [6] through which global warming of the eastern equatorial Pacific Ocean results in the development of unusually warm waters between the coast of South America and the ...
Following the El Nino event in 1997 – 1998, the Pacific Marine Environmental Laboratory attributes the first large-scale coral bleaching event to the warming waters. [169] Most critically, global mass bleaching events were recorded in 1997-98 and 2015–16, when around 75-99% losses of live coral were registered across the world.
El Niño is making a return after three straight years of La Niña weather conditions.
"El Nino often produces warmer and wetter winters, which can result in heavy snow and power outages. For the past 10 years, Generac has tracked and seen a 20% increase in (U.S.) power outages in ...
El Niños and their opposites, La Niñas, are naturally occurring weather phenomena that usually appear every two to seven years as a function of how the Pacific Ocean interacts with the air above it.
On February 9, the NOAA made a new ENSO forecast stating that the La Niña is still ongoing but will transition into an ENSO-Neutral soon. It says that there is around a 5% chance that the La Niña persists throughout March and around a 95% chance of an ENSO-Neutral in March. NOAA announced an El Nino later in the year. [4]
The El Nino weather pattern that can cause extreme events such as wildfires and tropical cyclones is forecast to swing back into generally cooler La Nina conditions later this year, the World ...
During a positive phase the waters in the western Indian Ocean are much warmer than normal and this can bring heavier rain regardless of El Niño. However, when both a positive IOD and an El Niño occur at the same time then the rains in East Africa can become extreme. [2] [3]
