The dreaded polar vortex is bringing its icy grip to parts of the U.S. thanks to a blast of warm air in the Arctic, as sudden stratospheric warming caused a mass of cold air to move southward. Scientists see a connection between climate change and differences in atmospheric pressure that causes slower moving waves in the air that contain the polar vortex.
