Will La Niña make this winter colder?
Authoritative response is coming
Xinhua News Agency, Beijing, November 4 (Reporter Gao Jing) Jia Xiaolong, deputy director of the National Climate Center, said on the 4th that the cold air affecting my country is more frequent this winter, and the forces are generally strong. The northwest route is the main route, and most of the country’s temperature is close. The same period of the year to low.
At a press conference held by the China Meteorological Administration on the 4th, Jia Xiaolong introduced that precipitation in the north will be more in the north than in the south this winter.
Affected by La Niña, the overall conditions of water vapor transportation in the south are deviated and precipitation is low.
He introduced that starting from August this year, the sea temperature in the Central and Eastern Pacific entered the state of La Niña, and a weak to moderate La Niña event is expected to form in winter.
Generally speaking, in the winter affected by La Nina, the cold air that affects our country is more frequent, and the probability of low temperature in the central and eastern regions and most areas is relatively high.
"But we have also noticed that in the context of global warming, the relationship between the various climatic factors affecting our country is very complicated. La Niña is only one of the important factors affecting our country's winter climate." He said that the prediction of the winter climate should be based on Comprehensive consideration of multiple factors.
Jia Xiaolong pointed out that my country's climate change is very obvious in stages this winter.
In the early part of the winter, with the exception of low temperatures in western Inner Mongolia, northwestern China, and southern China, temperatures in most parts of the country were normal to high.
However, around January next year, the cold air forces affecting our country will be significantly stronger. The temperature in most of the central and eastern regions may be lower than normal. A wide range of low-temperature rain and snow may occur in the northern region. Take precautions.
The possibility of a large-scale and continuous low-temperature rain, snow and freezing disasters in the south is relatively small, but a phased low-temperature rain, snow and freezing weather process may occur in parts of the southwestern east and parts of the Jiangnan area.
In addition, he introduced that affected by frequent cold air, it is expected that the meteorological conditions for air pollution diffusion in the Fenwei Plain and the surrounding areas of Beijing-Tianjin-Hebei will be close to the average level of the past five years this winter.
