The polar vortex is a large area of low pressure and cold air surrounding both of the Earth’s poles. It ALWAYS exists near the poles, but weakens in summer and strengthens in winter. The term "vortex" refers to the counter-clockwise flow of air that helps keep the colder air near the Poles.

Overview. Almost one year to the date of another brutal cold snap (January 14-17, 2024), a portion of the Polar Vortex delivered bitterly cold conditions to broad swaths of the continental U.S. for several consecutive days.The "Polar Vortex" simply refers to a large area of low pressure and cold air surrounding both of the Earth’s poles which is always present during the winter.
