In the Pacific, the northern hemisphere is experiencing rainier, rainier and cooler weather, a moderate and strong La Niña weather anomaly, and with a 90 percent chance that conditions will persist by the end of the year, Napi.hu wrote following the BBC news. . According to a recent forecast published by the World Meteorological Association, the British civil service has a 55% chance that the conditions feeding La Niña will persist even into the first quarter of 2021.
All this means that the climate will be colder than usual around the world, while in some places the amount of precipitation will multiply as usual and in some places it will cause drought. La Niña forms when a strong easterly surface wind moves from South America to Indonesia into the warmer surface waters of the Pacific Ocean, which are replaced by cold water from below. Once on the surface, cool the air above it.
This meteorological anomaly mainly causes significant rainfall in Indonesia, Australia and stronger monsoons in Southeast Asia. In the Northern Hemisphere, it causes colder and heavier snow storms in Canada and the northern US, and more rain than usual in the British Isles and northern European countries. La Niña was last founded in 2010-2011.
The Arctic Ocean has not started to freeze, which could completely alter weather conditions.
However, the warming atmosphere and climate change mean that it is hotter today in La Niña times than in previous El Niño periods. 2020 still stands a good chance of competing for the title of the hottest time ever experienced, and the 2016-2020 period is expected to be the hottest half-decade since the start of meteorological records.
