Chicago will be colder than parts of the Antarctic this week



If you've been getting the news on or going out recently, you're familiar with the record-breaking cold that's been rampant across North America. After The Washington Post early in 2019, a mass of bony air split over Canada – a polar vortex – into three parts, one of which can strike the eastern US polar vortex, cold air straight out of the Arctic Tundra in more temperate regions. But what is the weather phenomenon?

How is a polar vortex created?

Polar eddies are basically arctic hurricanes or cyclones. NASA defines it as "a swirling and sustained large area of ​​low pressure that is typically found across northern and southern poles." A winter phenomenon, swirls occur when the sun sinks above the pole and cools the temperatures, and in the middle and upper Troposphere occur and the stratosphere (approximately between six and fifty kilometers above the Earth's surface).

Where does a polar vortex meet?

In the northern hemisphere, the vortices are moving counterclockwise. They usually fall down over Canada, but according to NBC News, polar swirls can infiltrate the adjacent US due to the warm weather over Greenland or Alaska ̵

Polar vortexes are not & # 39; Rarely – in fact, arctic winds sometimes plunge into the eastern US – but sometimes the sheer size of the affected area is much larger than normal.

How cold is a polar vortex?

So cold that frozen sharks are known to wash themselves on the beaches of Cape Cod. So cold that the pet owners at the Calgary Zoo in Alberta, Canada, once decided to bring their group of king penguins in for heat (the species lives on islands north of Antarctica and the birds are not used to extreme cold.) In Alabama and other regions of the Deep South, single-digit temperatures and wind gusts were below zero.

But fortunately, this Arctic frost will not last forever: temperatures will rise gradually. 19659010] (function (d, s, id) {
