Anybody have any ideas? I've been looking for a good measure of the cold spinning around 2 cold poles, one over the Canadian Archipelago and one spread out across Siberia. What's a good way to capture this empirically?
I'm not sure I understand what's being shown by wind vector anomalies in the 850-200mb range. It does locate along the date line / GMT axis.
Specifically what i'm interested in is the tendency of the ridging from the Pacific and Atlantic to reach the pole and isolate the two cold pools into two counterclockwise rotating patterns. Was this dual counterclockwise pattern predicted? Has it been studied? I dare ask, is it new? Is it a function of weather oscillations or purely the polar cell breaking apart in front of our eyes?
Sorry about the size of the gifs. I'm on LTE myself.
