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]
The Pacific Ocean and surrounding areas. The 2023–2024 El Niño was regarded as the fifth-most powerful El Niño–Southern Oscillation event in recorded history, resulting in widespread droughts, flooding and other natural disasters across the globe. The onset was declared on 4 July 2023 by the World Meteorological Organization (WMO) [1][2 ...
The El Niño–Southern Oscillation affects the location of the jet stream, which alters rainfall patterns across the West, Midwest, the Southeast, and throughout the tropics. The shift in the jet stream also leads to shifts in the occurrence of severe weather, and the number of tropical cyclones expected within the tropics in the Atlantic and ...
A major key to shaping weather patterns worldwide is found in the tropical Pacific Ocean, far from any mainland. Known as the El Niño-Southern Oscillation (ENSO), this climate phenomenon is the ...
El Niño is part of a regular climate cycle known as the El Niño-Southern Oscillation (ENSO). It occurs when sea surface temperatures in the equatorial eastern Pacific rise to above-average ...
El Niño is one of three phases of the El Niño Southern Oscillation, which tracks water temperature changes in the equatorial Pacific Ocean that can have rippling effects on weather patterns ...
The Pacific Ocean and surrounding areas. The 1997–1998 El Niño was regarded as one of the most powerful El Niño–Southern Oscillation events in recorded history, resulting in widespread droughts, flooding and other natural disasters across the globe. It caused an estimated 16% of the world's reef systems to die, and temporarily warmed air ...
The progression from El Niño to La Niña, which is part of a broad system called the “El Niño Southern Oscillation,” or ENSO, is the result of conditions in the tropical Pacific. During the ...
