The sudden stratospheric warming weakens the polar vortex (a very large, rotating low-pressure system located near the north or south pole), which causes freezing Arctic air to move southwards.

A polar vortex collapse is an event that occurs when the layer between 10km and 50km above Earth’s surface warms up to 50 degrees in just two days. This scientific phenomenon is known as sudden ...
