Major Polar Vortex rearrangement

~Siberia gets back it's freezing mojo
~Canadian Arctic Upper Air is remarkably warm
~A confluence of wider Arctic Ocean open water and thinner North of Greenland sea ice killed the great Canadian  Arctic Archipelago super cold vortex of 2018 about 10 days ago
~Asymmetric in size Arctic Polar vortex consequences for winter 18-19



09 0000 UTC CMC 700 mb chart with colour ( by me),  blue zone -20 to -25 C,  pink -25 to -30,  red below -30 C.    Demonstrates a great disparity in coldest  temperatures between North America and Eurasia,  Siberia regained its famed coldest weather in the Northern world.   While the North American side will undoubtedly be varnished with a much warmer winter with strange Polar Vortex rogue vortices causing sudden extreme weather events.    Such example is happening now,  a midwest North American vortice  formed colder than anything currently  in the Arctic,  it is not a cold from the Arctic blast,  it is a very exotic,  I would say interesting,  rogue vortice which will cause havoc over a much larger Anerica basking in above average weather.    On the other continent,  if this is the coming winter Polar Vortex arrangement,   UK, Scandinavia and Moscow will be wet like London of old.  While Japan and Alaska will benefit with much warmer and yes wet weather. 

   As far as sea ice is concerned,  it was to blame for this climate rearrangement.  In near total darkness CAA never really got a chance to go deep cold,  because there was no Arctic Basin deep long night enhanced cooling, stopped by unprecedented open water North of Greenland,  which became thinner,  but still  releasing more heat ,  contributing in tandem with a once near 1 million km2 square wider open water  heat release bonanza ultimately decimating the great North American Vortex of 2018 ,  it nearly lasted a year.    The current  pumping of Pacific blob sea surface heat is reaching to near Greenland,  greatly impeding a strong Canadian vortex to form.    This new climate scene will cause a different ice accretion geographic distribution,  already drastically warming Bering sea area, no accretion ,  and cooling further  the North Pole (needed accretion),    the latter has sea ice already in place,  the former has open water not to freeze so fast....WD November 9 2018
