El Nino Now Not Appearing This Winter!

EL NINO IS NOW NOT FORECAST TO APPEAR THIS WINTER! 

Early data in Sept. indicated that we could have a developing El Nino this winter, but NASA Ocean surface temperature data has shown that the "warmer than normal" pool of water in the eastern Pacific Ocean that changes the course of the Jet stream and storms in the Northern Hemisphere, has not materialized. SO- Although I've told folks that if we had an El Nino winter, it would be colder and snowier, now there's no need to worry about it. It looks like an Average Winter for the Mid-Atlantic and Northeastern U.S.

Adios, El Niño. Forecasters have called off predictions for a wet winter in the West, finally acceding that ocean temperatures in the Pacific show no signs of the infamous El Niño phenomenon.

Weather experts at the Climate Prediction Center (CPC) first warned of developing El Niño conditions in June. An El Niño is the warming of the equatorial Pacific Ocean, which results in major droughts in Southeast Asia and wet winters for the southwestern United States. In a boon for the battered Northeast, an El Niño would have meant less wintry weather there.

But in the following months, sea-surface temperatures failed to warm enough to shift global weather patterns. In early October, the CPC dropped the odds of an El Niño from 70 percent to 55 percent.

Finally, the CPC, part of the National Oceanic and Atmospheric Administration (NOAA), called off the El

Nino forecast Thursday (Nov. 9). "The previous El Nino watch has been discontinued as the chance of 

El Nino has decreased," the CPC said yesterday in its monthly report.

It depicts places where the Pacific sea surface height is higher than normal (due to warm water) as yellow and red, while places where the sea surface is lower than normal (due to cool water) are shown in blues and purples. Green indicates near-normal conditions.

While chances of El Nino seem nil, the CPC said tropical ocean temperatures may still remain above

average.

Instead of El Niño, NOAA predicts that the neutral phase of the El Niño/ La Niña Southern Oscillation (ENSO)index will prevail. Jokingly called "La Nada," it is the neutral middle ground between El Niño and La Niña (associated with cool water in the equatorial Pacific).

El Niño expert Bill Patzert first pegged the La Nada back in June. "The equatorial Pacific is neutral, with no El Niño developing... not even a hint," said Patzert, of the Jet Propulsion Laboratory in Pasadena, Calif., in June. Even as ocean temperatures warmed slightly, Patzert said he maintained the call.

"The atmospheric support never developed, and I was saying weak El Niño maybe, but basically La Nada," Patzert told OurAmazingPlanet in an email. "I wanted an El Niño, but I just couldn't make it happen."

La Nada makes storms more difficult to predict. Without ENSO's influence on storm patterns, forecasters lack a predictable guide for winter temperature and precipitation throughout the United States. For example, El Niño means more rain and snow in the south and the phenomenon even calms hurricanes in the Atlantic.
