On November 19, international meteorological experts simultaneously issued a warning about a notable weather phenomenon. According to the latest weather forecast, in the upper atmosphere of the Arctic, a major change is taking place and it is expected that in the next 10 days, it will reverse weather patterns, creating the premise for a cold and snow-filled December covering the entire Northern Hemisphere.
This is considered one of the most significant and earliest extreme cyclone disruptions recorded since the satellite era.
In terms of mechanism, the extreme cos cosine system in the atmosphere acts as a giant "wind wall", with the task of locking in the super cold air mass remaining in the Arctic.
When this wall is solid, the cold will be retained in the North. However, as it weakens, the cold air mass will move south, directly affecting areas such as North America, Europe and Asia.
Currently, observation data shows that the air in the atmosphere is heating up rapidly and suddenly. This phenomenon is called "the sudden heating up of the average layer".
The paradox is that this heating up above leads to cold prices below ground. Ms. Amy H. Butler, a meteorologist at the National Oceanic and Atmospheric Administration (NOAA), explained that this warming is causing tornado winds to weaken and even reverse.

It is forecasted that in the next 2 weeks, when the cyclone is extremely weak, it will feel like a slowing spinning and starting to shift away from the orbit. As a result, cold air masses will exhale and move south.
Mr. Judah Cohen, a scientist at the Massachusetts Institute of Technology (MIT), commented that the most unusual point of this event was the timing. Sudden heating of the average layer with such an intensity was almost unprecedented in November.
While it is not yet possible to accurately predict the specific drop point, scientists are closely monitoring the possibility of temperatures dropping below normal in mid-latitude areas - home to the majority of the world's population - in the coming month.
once a severe tornado breaks, it could take a month or more to recover, says Andrea Lopez Lang, a meteorologist at the University of Wisconsin-Madison. "Although the center of the world is thousands of kilometers above us, it connects with our weather through invisible threads," Ms. Lopez Lang von said.
Historical data shows that similar events in early winter often lead to a colder, more snowy December. This means that North America, Europe and part of Asia need to prepare for the upcoming severe cold spells.
