Meteorologists warn that the coldest explosion in the Arctic air this season will come to put an ice marvel in the winter of America from the repeated polar cycle invasions. It will remain frozen there throughout the next week.
Various weather forces in the Arctic gathered to push cold air, which usually remains near the Arctic not only in the United States, but also Europe, as many meteorologists told the agency.
This will be The tenth time This winter Antarctic vortex Judas Cohen, director of seasonal prediction in private and environmental cover, said that the coldest air in the Arctic that was formulated at the top of the world – extends like the rubber band to send some of this large cold in the south. In normal winter, perhaps it may happen two or three times.

This winter, with Snow record in New Orleans Drought and Destroyed forest fires In southern California, it was not normal.
The latest expected The outbreak of the cold The Northern Rockies and Northern Plains team should first hit Saturday and then stick to it all over the next week. Meteorologists said that the cold would likely focus on east of Rocky with the West of America only, and the exempt central Florida.
On Tuesday, he expected the average of 48 states less than 16.6 degrees Fahrenheit (minus 8.6 ° C), then sliding to 14 degrees (minus 10 ° C) on Wednesday, and the account of the chief scholar.
Meteorologists expect to make the strong winds feel the worst. Every American state, but Hawaii, California and Florida have some or all parts that expect a good chance Wind of 20 degrees or less At some point next week, national weather service predicted.
Zach Taylor, meteorologist at weather service forecasts, said that Kansas, Nebraska, Missouri and Iowa will be “more impressive”, with temperatures up to 35 degrees (19 degrees Celsius). center. On Wednesday, NOAA weather models predict a lower zero in Oklahoma, Colorado, Nebraska, Missouri, Illinois, Iowa, Kansas, Wyoming, Montana, North Dakota, South Dakota, Minnesota, Wisconsin and Michigan.
Taylor said that some storms – with floods, thick snow, or even light – can strike during the outbreak of the long cold next week, but the details about those are not certain yet.
Mao said: “Everything, all the stars are aligned, all the wind directions in the atmosphere pull the cold polar air from the Canadian Arctic.” It is the depths of winter. Everything indicates extreme biting, cold winter. It is clear that this is not the first polar spiral ring in the winter, but it appears to be the most intense. “
Cohen said that an extended polar spiral like this occurs in the atmosphere and differs from when the polar cycle is sudden heating and weakens and escapes all cold air south and outside the columns. During the extended events, the polar vortex is still in place and strong, but it also pulls and bends. Extension outbreaks are usually a little more moderate than large polar escape events and often strikes the United States, not Europe.
“Meteorologists want to study the reason for this expansion often this year, but it may be just a natural random.
“What we notice now is interesting, but he has not been unprecedented,” said Martin Standel, a scientist at the National Climate Research Center in Denmark.
Another factor that adds to the extension of the polar spiral is a large point of high pressure in the upper atmosphere over Greenland. Cohen said he is moving west and will push the river course – the air river that moves weather systems such as storms – to a pattern that causes polar air down and staying there.
The climate change caused by a person may be made The full flow of the full flow is likely to be stuck in this wavy styleStandel said one of the factors concerned.
Mao said that there are many winter in the past in the past to help meteorologists predict what will happen after that and when the cold will disappear.
Despite the unusually cold winter throughout the United States, the world remains in the general warming pattern. The average total temperature for the Earth is another monthly thermal record in January. It was the eighteenth month of the last 19 years that hit or passed the world at the international level Warming limit 1.5 degrees Celsius (2.7 A) Above the pre -industrial times.
