Blamed for drought and record snow, La Nina revives
* Sea surface temperatures cool in equatorial Pacific
NEW YORK, Sept 8 (Reuters) - The dreaded La Nina weather anomaly, blamed
for both drought and record snowfall in the U.S., has returned and will
garner strength during the coming winter, the U.S. Climate Prediction
Center forecast Thursday.
"While it is not yet clear what the ultimate strength of this La Nina
will be, La Nina conditions have returned and are expected to gradually
strengthen and continue into the Northern Hemisphere winter (of) 2011-12,"
the CPC said in a monthly update.
It said waters in the eastern half of the equatorial Pacific Ocean
cooled in August, and the "oceanic and atmospheric patterns reflect the
return of La Nina conditions."
The CPC is an office under the U.S. National Oceanic Atmospheric
Administration. It issues monthly reports on the El Nino and La Nina
weather phenomena. Both weather patterns often follow one another in the
Pacific.
El Nino is an abnormal warming of waters in the Pacific and led to the
failure of India's vital monsoon in 2009/10.
La Nina is the opposite and is often linked to the ramping up of storms
in the Atlantic basin which threaten oil rigs in the Gulf of Mexico.
It has already been an active storm season, with Hurricane Irene
running up the U.S. East Coast and wreaking havoc through heavy rains and
floods from North Carolina to Vermont bordering Canada.
Currently, three systems were being tracked in the Atlantic Ocean and
Caribbean Sea which may threaten the U.S. Gulf and East Coasts.
La Nina was blamed in part for the severe snow storms which struck the
U.S. last winter and the worst drought in a century which has ravaged Texas
and swathes of the southwestern part of the country.
El Nino means "little boy" in Spanish and was named after the Christ
child when it was first observed by Latin American anchovy fishermen one
Christmastime in the 19th Century. La Nina means "little girl" in Spanish.
