Watch out for the Polar Vortex (or not)

This blog is turning into the debunk what people are miss-calling things blog (or something like that...)
The current cold snap coming to most of North America (Except Manitoba which is always this cold...) has been described by not just a few as the polar vortex. Which is partly true but mostly just wrong.
Some people even in the weather community have been saying that this is caused by the polar vortex, and while it is involved it's not a vortex of cold are screaming southward like a tornado as some people seem to think.
Our world spins and has two poles. The south one has mountains and glaciers so the winds don't form as much at the pole itself but as a ring of storms and wind off of the edge of Antarctica as well as a tight polar vortex.
The north pole has just ocean, aptly named the arctic ocean, where the winds form a tighter circle around the pole. This is the northern polar vortex; it keeps the coldest arctic air bottle up at the pole. And while it is stable it just whips around the pole because of the spin of the earth, sort of, plus some other stuff like heat transfer from the south. Every once in a while every spinning thing breaks down. An interference wave caused by the land masses around the pole, Greenland for instance, and the weather there, cause the breakdown and this is what happened here, the vortex broke letting the cold air contained within to spill out.
When this happens the resulting southward moving air blasts through the warmer air and disrupts all kinds of things and can form into little low pressure vortex storms like what has hit the US east coast. These are not the polar vortex but the air that was once contained by the polar vortex. While they go south warm air has to replace it at the pole (warmer, not really all that warm) and then the next polar vortex forms and that air gets cold and eventually it all happens again.
