The strengthening El Niño in the Pacific Ocean has the potential to become one of the most powerful on record, as warming ocean waters surge toward the Americas, setting up a pattern that could bring once-in-a-generation storms this winter to drought-parched California.
The National Weather Service’s Climate Prediction Center said Thursday that all computer models are predicting a strong El Niño to peak in the late fall or early winter. A host of observations have led scientists to conclude that “collectively, these atmospheric and oceanic features reflect a significant and strengthening El Niño.”
“This definitely has the potential of being the Godzilla El Niño,” said Bill Patzert, a climatologist with NASA’s Jet Propulsion Laboratory in La Cañada Flintridge.
Patzert said El Niño’s signal in the ocean “right now is stronger than it was in 1997,” the summer in which the most powerful El Niño on record developed.One of the reasons we re-posted 'El Niño: "The ARkStorm Scenario Could Flood California's Central Valley Like a Bathtub and Cost $725 Billion"' last week.
“Everything now is going to the right way for El Niño,” Patzert said. “If this lives up to its potential, this thing can bring a lot of floods, mudslides and mayhem.”
“This could be among the strongest El Niños in the historical record dating back to 1950,” said Mike Halpert, deputy director of the Climate Prediction Center.
After the summer 1997 El Niño muscled up, the following winter gave Southern California double its annual rainfall and dumped double the snowpack in the Sierra Nevada, an essential source of precipitation for the state’s water supply, Patzert said.
A strong El Niño can shift a subtropical jet stream that normally pours rain over the jungles of southern Mexico and Central America toward California and the southern United States.
But so much rain all at once has proved devastating to California in the past. In early 1998, storms brought widespread flooding and mudslides, causing 17 deaths and more than half a billion dollars in damage in California. Downtown L.A. got nearly a year's worth of rain in February 1998.
During the second largest El Niño on record, in the winter of 1982-83, damage was particularly severe along the coast, especially when powerful storms arrived as high tide surged onto the coast. "Particularly at the end of January 1983, we had some very strong storm wave effects along the coast, and a lot of the vulnerable structures were lost that winter," said Dan Cayan, climate researcher with the Scripps Institution of Oceanography at UC San Diego and the U.S. Geological Survey.
"Many locations along the California coast recorded their highest sea levels during that winter," he said...MUCH MORE
