High up in the atmosphere, there's a ring of cold air swirling over the Arctic that can intensify, weaken, and shapeshift through the seasons. This is the polar vortex. If it gets disrupted, this twisting pool of chilly air can influence the weather we experience, increasing the risk of a cold snap in the Northern Hemisphere. Current observations show the vortex has weakened unprecedentedly early this year, with its winds reversing directions. It's not yet clear how the current disruption to the polar vortex will affect the Northern Hemisphere winter, but scientists agree it is a record-breaking event.
