He polar vortex has changed the address of its turn. The polar vortex is that giant area of cold air that surrounds the Earth’s poles.. Scientists have reported that time turns “backwards”, in a radical alteration that is raising questions and concerns among experts.
The polar vortex, according to NOAA (National Oceanic and Atmospheric Administration), is characterized by its counterclockwise rotation, which helps keep air cold near the poles.
The pattern of movement of polar vortex has been completely reversed. What does this mean for us?
The polar vortex changes its direction
This change is not as unusual as we might think. During the summers In the northern hemisphere, winds from the vortex They tend to slow down and turn clockwise. But what is truly strange is that this alteration is happening months before summer.
According to specialists, this reversal is one of the six most intense since 1979. This indicates that we are facing a rare event, and scientists are faced with the task of discovering its possible consequences.
What can we expect with the change of the polar vortex?
Although the repercussions of this event have not yet been clearly defined, notable changes have already been observed. For example, a registered increase in ozone levels over the Arctic. Although this has not generated drastic meteorological changes, everything is expected to return to normal when the vortex recovers its usual direction.
However, uncertainty is exacerbated by the global warming. How this phenomenon interacts with the vortex reversal is still a mystery to scientists.
This situation has put the polar vortex under the spotlight like never before. Scientists are more concerned than ever to understand what is causing these unusual changes and what other consequences might come with them.
It is not one vortex, but two
In reality, there are of polar vortices: one in the northern hemisphere and one in the southern hemisphere. The northern polar vortex is the one that affects us the most in Mexicosince it is the one that has the greatest influence on the climate of our country.
He polar vortex It is composed of extremely cold air, with temperatures that can reach -80°C. This cold air is kept in the vortex thanks to the force of the jet stream, a band of very strong winds that circulates around the planet.
The polar vortex is not a permanent structure, but can weaken or even fragment into smaller pieces. When this happens, the cold air vortex It can escape to the south, which can cause intense cold waves in some regions, as happened in September 2023 and January 2019.
