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]
El Niño finally lost its grip on global weather in June, but La Niña’s arrival was delayed repeatedly, leaving an extended period of neutral conditions in place through the summer and fall.
La Niña, which translates to "little girl" in Spanish, and El Niño, which translates to "little boy" in Spanish, are two phases of a three-pronged natural climate pattern that occurs across a ...
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 ...
A markedly increased Walker circulation causes a La Niña by intensifying the upwelling of cold deep sea water; which cools the sea surface to below average temperatures. During non-El Niño conditions, the Walker circulation is seen at the surface as easterly trade winds that move water and air warmed by the sun toward the west.
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 ...
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 ...
