Global Circulation flipped by mega blizzard with no wind directions change for a week at 40 to 50 knots.

~CAA  Cold Temperature North Pole captured a Low otherwise on its way to NW Europe
~The dynamics were similar to  heat machine fueled by the temperatures contrast between  warm and cold, open Oceans and a frozen Arctic scape.

    A remarkable blizzard spanning a great deal of the Northeastern Canadian  Arctic essentially made winds  coming from a rock steady direction for weeks.    Record temperatures warmed all of the Canadian Arctic Archipelago for the same time period,  heat injected from the oceans displaced and weakened and moved the CAA Cold Temperature North Pole,  which had garnished cooling for months,  further to the South and West in a matter of days.   What happened was a matter of weather dynamics which forced two main geophysical opposites,  warm and cold atmospheres in a fused static stalemate:

From 18th to 24 November this CMC 22 November surface analysis is the picture of the blizzard week.  A perfect,  stuck in place,  heat engine with heat from the East open sea waters meeting the coldest air in the Northern world head on.     At first,  the center of cold was  steady strong over the center CAA:

The main dominant cold air zone of the Northern Hemisphere had a weaker twin Northeastern Siberia,  in between  huge strong anticyclone,  which given the right conditions,  can push the strong CAA CTNP  southwestwards.  The arrival of a low pressure centered about Hudson Bay was just what was needed.  And so the biggest pan Canadian Arctic mega blizzard of 2017 happened with a trowal which lasted as long as the Hudson Bay Low persisted.    As  a result ,  record warming reigned throughout the Canadian high Arctic .      This Low didn't move for a week along with static wind directions everywhere. 

     Global weather circulation was thus changed  in a few days,  making Northeastern Siberia coldest atmosphere at present.  But this is changing quickly,  as the CAA permafrost was seriously cooled prior to this warm air advection, which means that the CTNP will soon return to dominate on the Canadian side of the Pole.wd November 25,2017
