El Nino At Play As Source Of More Intense Regional US Wintertime Storms
Greenbelt MD (SPX) Jan 29, 2008
The next time you have to raise your umbrella against torrents of cold winter rain, you may have a remote weather phenomenon to thank that many may know by name as El Nino, but may not well understand. Researchers now believe that some of the most intense winter storm activity over parts of the United States may be set in motion from changes in the surface waters of far-flung parts of the Pacifi ... more
NASA Observes La Nina: This 'Little Girl' Makes A Big Impression
Greenbelt MD (SPX) Jan 14, 2008
Cool, wet conditions in the Northwest, frigid weather on the Plains, and record dry conditions in the Southeast, all signs that La Nina is in full swing. With winter gearing up, a moderate La Nina is hitting its peak. And we are just beginning to see the full effects of this oceanographic phenomenon, as La Nina episodes are typically strongest in January.
A La Nina event occurs when cooler ... more
NASA Data Captures El Nino Return In The Pacific
Los Angeles CA (JPL) Oct 09, 2006
NASA satellite data indicates El Nino has returned to the tropical Pacific Ocean, although in a relatively weak condition that may not persist and is currently much less intense than the last major El Nino episode in 1997-1998.
Over the past several weeks, NASA's Aqua and Jason satellites have observed a general warming of ocean temperatures and a rise in sea surface heights in the central ... more
Weak To Moderate El Nino Until Early 2007
Geneva (AFP) Sep 26, 2006
The climatic phenomenon El Nino should gather weak to moderate intensity, leading to a warming of the Pacific Ocean, the World Meteorological Organization said Tuesday. "Climate patterns across the equatorial Pacific over the last one-two months have developed a notable tendency toward El Nino conditions," the WMO said in a statement.
"There is general agreement that 'the development of a ... more
Pacific Recycles Last Year's Winter
Pasadena - Nov 7, 2001
The Pacific ocean continues to be dominated by the Pacific Decadal Oscillation, an above normal sea level pattern that is larger and stronger than any El Nino/La Nina event, according to the latest information from the U.S.-French Topex/Poseidon ocean-monitoring satellite.
"It is striking how similar October 2001 looks to October 2000," said Dr. William Patzert, an oceanographer at NASA's Je ... more

Boosted by the influence of a larger climate event in the Pacific, one of the strongest La Ninas in many years is slowly weakening but continues to blanket the Pacific Ocean near the equator, as shown by new sea-level height data collected by the U.S.-French Jason oceanographic satellite. This La Nina, which has persisted for the past year, is indicated by the blue area in the center of ... read more
