La Lina responsible for snow disaster in China

According to the Chinese meteorologist "the rare prolonged snowstorms and low temperatures that have caused havoc in many parts of China are mainly related to the La Nina phenomenon and abnormal atmospheric circulation" said Du Guodong.
The severe weather strongly resembled the aftermath of La Nina events, which indicated that the latest development of La Nina was a primary cause of the abnormal snow, meteorologists at the Jiangxi Provincial Meteorological Bureau said, reports Guodong.
La Nina is a large pool of unusually cold water in the equatorial Pacific that develops every few years and influences global weather. It is the climatic opposite of El Nino, which is a warming of the Pacific.
"Experts said that the latest La Nina conditions developed last August throughout the tropical Pacific and strengthened at the sharpest pace in 56 years. The sea-surface temperature during the past six months was 0.5 degree Celsius lower than normal years". "The La Nina weather pattern is expected to prevail at least till the end of spring," said Jiao Meiyan, director of the National Meteorological Center.
Chinese meteorologists also pointed out that the abnormal atmospheric circulation in some regions of Europe and Asia, which has persisted for nearly 20 days since mid-January, was responsible for the rampant chilly weather, rain and snowstorms.
Snow storms that hit 19 provinces in southern and central China, the worst in 50 years, have killed more than 60 people and forced nearly 1.8 million people to relocate over the past three weeks, inflicting economic losses of about 53.9 billion yuan (7.5 billion U.S. dollars), according to the Ministry of Civil Affairs on Friday.

Lin Li reporting from Bejing said that"the Chinese President Hu Jintao called on the public on monday to hold the firm belief on victory over the weather crisis that is still plaguing the southern part of the country". "Chinese Premier Wen Jiabao said here on monday that china is confident and capable in achieving the final victory in combatting disasters incurred by low temperature, ice and heavy snow".
