A major current of circulating air called the Arctic polar vortex has completely reversed course and is now spinning ‘backwards’. With winds now blowing easterly, scientists are trying to predict what effect this might have on weather systems in the coming months.

Before you start envisioning the sudden collapse of our planet’s weather systems, these reversals aren’t all that unusual. While the strength of the reversed winds has attracted attention, this is not the first reversal this year. During the summer months in the Northern Hemisphere, the vortex’s circulating winds slow down and start spinning easterly (clockwise around the Arctic) too.

However, reversals from westerly to easterly during the winter months can have significant impacts, and few are as dramatic as the one we’ve seen in March 2024.
