The El Niño–Southern Oscillation is a single climate phenomenon that quasi-periodically fluctuates between three phases: Neutral, La Niña or El Niño. [12] La Niña and El Niño are opposite phases which require certain changes to take place in both the ocean and the atmosphere before an event is declared. [12]
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 ...
Fall is in full swing, but it’s not too soon to look ahead to winter, especially one that could feel considerably different than last year’s dominated by El Niño. A weak La Niña is expected ...
The World Meteorological Organization, an arm of the United Nations, estimates the likelihood of an El Niño developing in May or June at 60%, with the probability increasing to 80% by October.
The 2020–2023 La Niña event was a rare three-year, triple-dip La Niña. [1] The impact of the event led to numerous natural disasters that were either sparked or fueled by La Niña. La Niña refers to the reduction in the temperature of the ocean surface across the central and eastern equatorial Pacific, accompanied by notable changes in the ...
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
The third state is El Niño, which occurs when sea surface temperatures in the tropical Pacific rise to above-normal levels for an extended period of time. El Niño, Spanish for "little boy," was ...
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 ...
