A polar vortex (also known as an Arctic cyclone, sub-polar cyclone, Frigid Twister, and a circumpolar whirl) is a persistent, large-scale cyclone located near either of a planet’s geographical poles. On Earth, the polar vortices are located in the middle and upper troposphere and the stratosphere. They surround the polar highs and lie in the wake of the polar front. These cold-core low-pressure areas strengthen in the winter and weaken in the summer due to their reliance upon the temperature differential between the equator and the poles. They usually span 1,000â€“2,000 kilometers (620â€“1,240 miles) in which the air is circulating in a counter-clockwise fashion (in the northern hemisphere). As with other cyclones, their rotation is caused by the Coriolis effect.
The Arctic vortex in the Northern Hemisphere has two centres, one near Baffin Island and the other over northeast Siberia. In the southern hemisphere, it tends to be located near the edge of the Ross ice shelf near 160 west longitude. When the polar vortex is strong, the Westerlies increase in strength. When the polar cyclone is weak, the general flow pattern across mid-latitudes buckles and significant cold outbreaks occur.Ozone depletion occurs within the polar vortex, particularly over the Southern Hemisphere, which reaches a maximum in the spring.

Moral of the story
NASA Gravity Probe B (GP-B) has found that there is a space-time vortex around Earth, and its shape matches the predictions of Einstein’s theories of relativity. Time and space in Einstein’s theories of relativity, are woven together, forming the fabric of spacetime. As the Earth moves around the Sun the spacetime vortex moves around with it. Even the Earth spinning on its axis creates a spacetime frame-dragging effect.
A “deep down the rabbit hole” perspective to consider.
