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 ]
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.
The National Oceanic and Atmospheric Administration’s Climate Prediction Center says there is a 60% chance that a weak La Nina event will develop this autumn and could last until March. La Nina is part of a natural climate cycle that can cause extreme weather across the planet — and its effects vary from place to place.
That's because storm systems, mostly in the winter, move slightly northward with a shift in the jet stream during La Nina years, bringing more rain and snow north, L'Heureux said. Even though a La Nina tends to be cooler, there will likely be a residual effect of the exiting El Nino on global temperatures, L’Heureux said.
El Niño and La Niña are opposite phases of the same seasonal climate phenomenon known as the El Niño/Southern Oscillation in the ... La Nina 2024 impact on Rochester NY weather for the summer.
