The National Climate Center has announced that the La Nina phenomenon, which occurred in the equatorial Eastern Central Pacific Ocean beginning August, is predicted to make this winter colder-than-usual.
Since 1950, there were 14 La Nina occurrences which affected China's winter temperatures in 17 years. Data showed that except the winter of 1950, 13 of the remaining 16 years experienced colder winters.
La Nina is an ocean-atmosphere phenomenon characterized by low sea temperatures across the equatorial Eastern Central Pacific. It often occurs after a strong El Nino event. The global warming and La Nina phenomenon have caused China's coastal sea level to rise in recent years.
As temperatures in the western Pacific will be warmer than usual, conditions will be favorable to the formation of typhoons, bringing more severe freezing in winter, said National Marine Environmental Forecasting Center in August.
