Officially, Earth last experienced a La Niña event in the spring of 2023 and has been in an El Niño or neutral status ever since. 5 Weather Events To Watch For In 2025
Strong El Niños have recently been observed from 1997 into 1998 and from 2015 into 2016. The increased chance for El Niño comes after La Niña conditions were present for nearly three straight ...
La Niña’s arrival was a long time coming. Long-range forecasters at the CPC first raised the possibility of a switch to La Niña back in February 2024 when El Niño was still very strong. At ...
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 happens when Pacific waters cool, moving the tropical thunderstorms so that the wind shear in the Atlantic wanes during hurricane season. La Niña watch: High chances the hurricane ...
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 ...
L’Heureux said that La Nina’s tend to last longer and be more recurrent than El Nino events. “It’s unusual although it’s not unprecedented,” said Ben Cook, climate scientist at the NASA Goddard Institute for Space Studies affiliated with Columbia University, about the forecast for a possible La Nina this year.
Their results improved scientific understanding of the role of the ocean in climate change and improved weather and climate predictions. Data from these missions were used to improve ocean models, forecast hurricane intensity, and identify and track large ocean/atmosphere phenomena such as El Niño and La Niña. The data was also used in daily ...
