Tens of millions of people throughout the United States are faced with abnormally cold weather. The reason for this is an atmospheric phenomenon called the polar vortex (11olar vortex). We have collected photos and videos of Instagram users who will force someone to stay at home.
A polar vortex is a large area of cold air in the atmosphere. Such a whirlwind is a common occurrence in the Arctic and Antarctic, but in winter the area of cold air can increase and move further towards the equator.
According to some scholars
, such a movement of cold air indicates global warming.
The Midwest suffered the most from the polar vortex: in the Chicago and Northern Illinois area, the temperature dropped to 46 degrees below zero.
