The La Niña phenomenon is confirmed to have formed in 2020, is the cold wave of winter coming?
On October 29, Beijing time, the World Meteorological Organization released a new version of the”Global Seasonal Climate Update”, pointing out that this year’s La Niña phenomenon has been Formation, the expected intensity may be moderate to strong, and will continue until next summer.
World Meteorological Organization Secretary-General Taras also stated that El Niño and La Niña are the main natural driving factors of the Earth’s climate system, but currently All naturally occurring climate events may occur under the background of human-induced climate change. It reduces global temperature, exacerbates extreme weather, affects the global water cycle, and also brings more and more extreme weather, such as Africa The drought in the region, the blizzard in North America, and the southern region of China have also been affected to varying degrees. Extreme weather such as heavy rains, snowstorms and cold winters has become more and more frequent. Natural disasters have gradually intensified, accompanied by blizzards and cold waves. .
To put it bluntly, the La Niña phenomenon is the abnormally cold water in the central and eastern Pacific Ocean, which then leads to a series of global climate reactions.
La Niña actually means “La Ni?a” in Spanish—“little girl, saint”, which is the reverse of El Niño phenomenon, also known as “anti-El Niño” or “cold event”. It refers to a phenomenon in which the water temperature of the East Pacific near the equator drops abnormally. It is manifested as the obvious cooling of the East Pacific, and it is also accompanied by global climate chaos. Note that it always appears after the El Niño phenomenon.
Usually, the”La Niña phenomenon” generally tends to cause colder weather in winter, and cold winters and cold winters are likely to occur early. For example, in 2008, La Niña caused the temperature of the equatorial eastern Pacific to be about 0.5 degrees Celsius lower than usual, but only this 0.5 degrees caused strong cold air in Siberia and Mongolia all the way to the south. In the south, including parts of the Nanling Mountains, there have been multiple occurrences. Snowfall phenomenon. The weather is cold, the mountains and forests are frozen, the river is cut off, even trains, planes, etc. are suspended, and the highway is closed! So if this year is colder than 2008, what will it be like?
Humans are not Those who may conquer nature can only benefit the whole mankind by living in harmony with nature and maintaining ecological harmony.
As the saying goes, the extremes of things must be reversed. When the ultra-cold weather has passed, it will usher in a warm sky, and this extreme weather will cause a certain”cold disaster” to the earth, so dear readers, Time to prepare, put on winter clothes.
