The polar vortex is a massive, swirling band of cold air that normally traps frigid temperatures around the Arctic. However, recent scientific studies show this vortex is weakening, which could have ...

Not every cold snap is connected to the polar vortex, but when it does weaken, it can result in some of the lowest temperatures of the winter season in North America, AccuWeather added in the release.

As a result, it is expected to shift away from its polar residency, eventually sending cold air from the Arctic into North America and Eurasia.

The warmth expands the atmosphere and sends the Polar Vortex off the polar region and southward to either Eurasia or eastern North America. In this case, Cohen says the Polar Vortex will shift ...
