The World Meteorological Organization (WMO), which has announced the return of the La Niña phenomenon, has come up with a forecast for the coming winter in Europe. According to them, a mild winter awaits us, BTA reported. According to the organization, the cold Pacific current for the second year in a row will affect the planet’s climate. The La Niña phenomenon is expected to continue until the beginning of 2022 and, according to forecast models, to be weaker than in 2021.
Despite the cooling effect of La Niña, average temperatures this year are above long-term averages in many parts of the world. This is due to the record amount of greenhouse gases in the atmosphere, notes the WMO.
A mild winter is expected in most of Europe. Northeast Asia and the Arctic, as well as eastern North America, are also expected to be warmer, and northeastern North America, Australia, Southeast Asia and the Indian subcontinent are cooler than usual.
Because of La Niña, 2021 will not be the hottest year, but one of the 10 warmest, compared to the average of 1850 to 1900. The hottest year was 2016.
The La Niña phenomenon describes particularly high differences in atmospheric pressure in the Pacific between South America and Indonesia. As a result, warm surface water is pushed to Southeast Asia, and colder water rises from the depths. As a result, there is an increased atmospheric circulation of colder air, which reaches the Atlantic Ocean. This affects precipitation.
The La Niña climate phenomenon is the opposite of the El Niño phenomenon with a warming effect off the coast of South America.
In addition to the cooling effect, La Niña is usually associated with wetter conditions in some parts of the world and drier ones in others.
