Coupled with a winter storm and Increasingly low temperatures in the region As a result of climate change, the ravages of the meteorological phenomenon known as the polar vortex arrive: a circular spectrum of icy winds and low pressure swirls over the North Pole, about 50 kilometers above the Earth’s surface; When it expands, it feels its air outside the North Pole.
at the moment, Almost two-thirds of the US populationWith more than 200 million inhabitants, they are still waiting for what will happen in the next few hours and the protection measures issued by the authorities.

What is it and how does it affect the polar vortex?
the The polar vortex It is a permanent phenomenon that occurs in the Arctic and when it expands, it causes storms and frosts below the pole. Air currents reach speeds of up to 240 kilometers per hour during the winter season. The northern hemisphere is the most affected by the transit winds left by the eddy during this season.
The North American Weather System states that it is normal for the polar vortices to release icy currents to the south during this time because the pressure drops, resulting in strong movements of icy air across the area that does not always touch the ground; Storms may drift into the Pacific Ocean or advance into the Atlantic Ocean.
How to protect yourself from the polar vortex
Weather systems expect Friday afternoon to be the coldest in the southern part of the United States, specifically in Texas and in mountainous areas in some northern Mexican states.
