El Niño–Southern Oscillation (ENSO) is a global climate phenomenon that emerges from variations in winds and sea surface temperatures over the tropical Pacific Ocean. Those variations have an irregular pattern but do have some semblance of cycles. The occurrence of ENSO is not predictable.
The SOI is one measure of the large-scale fluctuations in air pressure occurring between the western and eastern tropical Pacific (i.e., the state of the Southern Oscillation) during El Niño and La Niña episodes.
Το Ελ Νίνιο (γνωστό και ως Ελ Νίνο, ισπ: El Niño) είναι το ωκεάνιο φαινόμενο κατά το οποίο τα κεντρικά και ανατολικά νερά του Ειρηνικού Ωκεανού κοντά στον Ισημερινό (ακτές του Περού) είναι ...
14 Νοε 2024 · El Niño and La Niña are the warm and cool phases of a natural climate pattern across the tropical Pacific known as the El Niño-Southern Oscillation, or “ENSO” for short. The pattern shifts back and forth irregularly every two to seven years, bringing predictable changes in ocean temperature and disrupting the normal wind and rainfall ...
Sea surface anomalies across the world in July 2023 during the 2023–2024 El Niño event. 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.
30 Αυγ 2009 · The Southern Oscillation Index (SOI) tracks the atmospheric part of the El Niño–La Niña climate pattern by comparing surface air pressure anomalies at Darwin, Australia, to pressure anomalies at Tahiti. The anomalies—departures from average conditions—indicate the strength of the Walker Circulation.
16 Απρ 2024 · El Niño is part of the natural climate phenomenon called the El Niño Southern Oscillation (ENSO). It has two opposite states: El Niño and La Niña, both of which significantly alter global...
