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 ...
NOAA's Climate Prediction Center (CPC) announced Thursday that water temperatures in critical parts of the Pacific Ocean had finally reached the threshold required for La Niña to emerge in December.
Last winter (2023-2024) was an El Niño winter marked by cooler and wetter weather for the southern states. The last La Nina ended in 2023 after an unusual three-year stretch. What about the rest ...
The past nine years have been the warmest on record despite the cooling effect of La Nina that spanned from 2020 to early 2023, according to WMO. (Reporting by Gabrielle Tétrault-Farber; Editing ...
In July 2023, the World Meteorological Organization declared that El Niño has developed in the tropical Pacific for the first time in 7 years. [76] In September 2023, the Bureau of Meteorology formally declared an El Niño weather event, for the first time in 8 years, after hot and dry conditions prevailed over south-east Australia during ...
[10]: 23 Future trends in ENSO due to climate change are uncertain, [11] although climate change exacerbates the effects of droughts and floods. The IPCC Sixth Assessment Report summarized the scientific knowledge in 2021 for the future of ENSO as follows: "In the long term, it is very likely that the precipitation variance related to El Niño ...
La Niña is a natural climate pattern marked by cooler-than-average seawater in the central and eastern Pacific Ocean. When the water cools at least 0.9 degrees Fahrenheit below average for three ...
The multivariate ENSO index, abbreviated as MEI, is a method used to characterize the intensity of an El Niño Southern Oscillation (ENSO) event. Given that ENSO arises from a complex interaction of a variety of climate systems, MEI is regarded as the most comprehensive index for monitoring ENSO since it combines analysis of multiple meteorological and oceanographic components.
