The term “polar vortex” refers to a large-scale weather pattern that occurs in the Earth’s atmosphere near the North and South Poles. It is characterized by a large area of low pressure and cold air that rotates counterclockwise around the pole. The polar vortex is strongest during the winter months, as the temperature difference between the poles and the equator is greatest at this time.
In 2025, an unusually strong polar vortex brought record-breaking cold temperatures to the state of Texas. The vortex caused widespread power outages, water shortages, and transportation disruptions. The event highlighted the vulnerability of the state’s infrastructure to extreme weather events.
