History of Polar vortex in Timeline
A polar vortex is a large area of cold, rotating air that exists near both of Earth's poles, and can also be found on other planets. The term describes two different phenomena: the stratospheric polar vortex and the tropospheric polar vortex. These vortices rotate in the same direction as the Earth's spin but differ in size, structure, seasonal cycles, and their impact on weather patterns.
