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 or El Niño are never the only factors influencing weather in a given season or location, but emphasis is placed on them because they typically have an outsized effect on winter weather ...
(Reuters) -The La Nina weather pattern characterized by unusually cold temperatures in the Pacific Ocean could emerge in the second half of 2024, following a strong El Nino year, a U.S. government ...
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 current El Niño is now one of the strongest on record, new data shows, catapulting it into rare “super El Niño” territory, but forecasters believe that La Niña is likely to develop in ...
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 ...
El Niño and La Niña greatly affect weather conditions worldwide. The last El Niño was in 2018-2019.
Weakening sea surface temperature anomalies in the tropical Pacific in early 2023 associated with the end of the La Niña event. The 2020–2023 La Niña event was unusual in that it featured three consecutive years of La Niña conditions (also called a "triple-dip" La Niña) in contrast to the typical 9–12 month cycles of the El Niño–Southern Oscillation (ENSO), [3] though the magnitude ...
