Polar Vortex

The polar vortex is a wind pattern surrounding the Earth’s poles. Both the North and South pole have polar vortices spinning around them. In both cases, the rotation is generally cyclonic — counter-clockwise around the North Pole and clockwise around the South Pole. While polar vortices exist year-round, they are strongest during each pole’s winter. Canadians tend to experience the effects of the North Pole’s polar vortex toward the end of winter. At this time, the vortex begins to weaken, and cold, polar air travels further south. Polar vortices are atmospheric phenomena which occur on other planets too, such as Mars, Venus and Saturn.
