El Niño unlikely to stay for the 2010 storm season.
El Niño, beloved in South Florida for hampering hurricanes, probably won't survive into the next storm season, experts say.
Although it's currently robust, climate models predict it will start to dissipate in the spring and disappear by summer. The atmospheric pattern on average lasts six to 12 months and almost never returns two years in a row, said Jon Gottschalck, head of forecast operations for the National Oceanic and Atmospheric Administration's Climate Prediction Center.
"The most likely scenario would be a neutral and possibly a weak El Niño surviving into the summer," Gottschalck said. "But there's a lot of uncertainty there."
For now, it's influencing our winter weather, making for wetter and cooler conditions than normal. And it remains a powerful force elsewhere around the globe.
Here's everything you wanted to know about the atmospheric pattern.
What is El Niño, exactly?
El Niño is a large-scale weather pattern that creates instability in the atmosphere. It is created by unusually warm waters — up to 10 degrees above normal — in the Eastern Equatorial Pacific Ocean.
The heat creates thunderstorm activity, which then triggers heavy tropical rainfall. That, in turn, results in a number of climatic consequences, among them chaos in the upper atmosphere.
