I was giving up on this, which has been the pattern for the last two years. In December, we had a Pacific plume penetrate the Arctic and cause all sorts of heck. Even today, the price of natgas has gone down.
The flow to Europe has stopped at the source, and we have an Arctic recharge vortex. This will keep going until the cold sludge tops Greenland, and it turns white (60 below). At that point, the cold air shoots like cold jelly on a plate. Most likely to Canada, but could go again to Europe.
I have purpose to my life now, watching this giant tip bucket fill up and dump. Look out natgas!
The usual time is 4 days, more or less.
ps remember, this is the Arctic Basin recharge vortex. It has the mechanics of filling up the basin with very cold, dense air. It is not the Polar Vortex, which can be anything in the media. We have had a bigger Giant Arctic Vortex, encompassing Greenland, but I think that was rare, and due to the heat incursion.

Keeping my tongue off the chain link posts. Just for my visualization, the vortex you mention is not stratospheric, but an airmass local and circulating in the polar region getting colder and colder…?
Peter of the…
Yes, the famous Polar Vortex doesn't have a definition that anybody sticks to. It can be anything. This is a standard thick atmosphere vortex.
