Is the term "Polar Vortex" something recently coined to describe a cold front?

It is much stronger than a polar express cold front. But, cold is cold, and gets the deer up moving.
A polar vortex is a persistent, large-scale cyclone that circles either of the planet's geographical poles. On Earth, the base of the polar vortices are located in the middle and upper troposphere and extend into 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 dependence upon the temperature differential between the equator and the poles.[1] They usually span less than 1,000 kilometers (620 miles) in diameter within which the air circulates in a counter-clockwise fashion in the Northern Hemisphere, and in a clockwise fashion in the Southern Hemisphere. As with other cyclones, their rotation is caused by the Coriolis effect.

Does the water in the toilet rotate backwards during a vortex?

Most of the old folk could "feel" it coming anyway.
