What is the polar vortex?
According to the specialized site Meteored, The polar vortex is a current of very intense winds that acts as a boundary between the colder air that is at the poles and the “warmer” air that is outside the polar regions.
This belt of strong winds blows west to east at an altitude of 15 to 30 kilometers above the stratosphere, so when it undergoes alterations, the colder air contained in the north pole can reach points closer to the south of the Earth.
This causes atypical weather conditions for the regions that are invaded by this wind system. Some of the conditions it generates are abrupt drops in temperature, intense snow storms, extreme winter conditions, among others.
Its effect usually lasts between 10 and 30 days, during which your cycle returns to normal.
At the moment, the weakening of the polar vortex has reached record values for this time of year; although there is still no specific reason why.

Although the specialists They assure that Mexico is not part of the countries with the greatest risks, they do point out that, in the same way, it will suffer the ravages of this process indirectly.
According to what they pointed out, the vortex modification could cause cold front activity to increase, as well as alter the path of winds, which means that low temperatures, strong gusts of wind and unusual variations in humidity and rain may occur.
