Polar vortex fairies may be 'out' this winter. Looks like everything is going to the dancing jet stream.
If we look at physics, then the jet stream is just the boundary between warm and cold and is merely a horizontal tubular storm. The hot air moves from west to east and dimples the cold air. It all looks like the jet stream is wiggling and rotating, when it is not.
We are getting one heck of a cold plume coming at us. This brings down the jet stream which can be said by philosophers to be the cause, a fine reversal. Can we go through a whole winter like this? Yes we can.
