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 ...
La Niña is considered the cool phase of the El Niño-Southern Oscillation (ENSO) and is characterized by lower-than-average sea-surface temperatures, with anomalies of at least -0.5 degrees ...
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 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.
The 1997–98 El Niño Event had various effects on tropical cyclone activity around the world, with more tropical cyclones than average occurring in the Pacific basins. . This included the Southern Pacific basin between 160°E and 120°W, where 16 tropical cyclones in the South Pacific were observed during the 1997–98 season compared to an average of aroun
El Niño doesn’t have as big of an impact on the Pacific Northwest in the spring and summer, National Weather Service meteorologist Joel Tannenholz previously told the Idaho Statesman.
The 2014–2016 El Niño was the strongest El Niño event on record, with unusually warm waters developing between the coast of South America and the International Date Line. These unusually warm waters influenced the world's weather in a number of ways, which in turn significantly affected various parts of the world.
