CTNP vortices avoiding Arctic Ocean sea ice , rapid warming of the Arctic transforms Polar Vortex morphology

 ~The speed of change is dramatic,  considering average warming by 1 C average use to take hundreds of years.  

~Arctic weather is morphing with respect to a warmer North Pole

   We look at recent CTNP vortices,  those coldest centers of the Polar Vortex,  at 600 mb pressure level, representing the temperature of the entire troposphere,  and find remarkable avoidance of the Arctic Ocean for having a Cold Temperature North Pole,  as surmised in previous articles,  they were interspersed, small, fleeting,  if any at all,  while similar over land at least lasting longer in duration or more stable:

CTNP's , the middle of coldest vortices found in the tropospheric Polar Vortex were remarkably bouncing all over the place in January 2022 finally settling into a major one over the Canadian Arctic Archipelago at January end.  But in the past.  CTNP's were not always Arctic Ocean shy:

Here we split the climate scenes made obvious in less than 30 years,  one in the 1970's and the other in last few years.  The contrast can't be more clear,  since 2007,  the Arctic Ocean seems to have been cleared of CTNP's,  while in late 70's it was 5 February 11's out of 6 which had CTNP presence,  rather than 1 out of 7 for 2007, 2016, 2018,2019 till 2022 same day.  The importance of taking a single day is not trivial,  since the area involved is huge, given same atmospheric chemistry, the odds are somewhere during the same day the temperatures would be similar.   Arctic Sea ice not as thick,  not as insulating from said but now warmer Ocean,  giving a different circulation pattern for the entire Northern Hemisphere,  which has not given pleasant or comfortable weather conditions in certain key locations of our planet.   WD Feb 12, 2022

When coldest of winter starts from the South, the new climate normal

 ~An Arctic perspective use to portray cold winds from the NORTH

~Now cold atmospheres start from the South

Pay attention to the High Arctic weighted temperature of the entire troposphere.  At beginning of January till mid month the coldest air was further South,  then after the Cold Temperature North Poles grew in size,  the coldest temperatures finally settled in the High Arctic.  This climate shift is recent.  Basically implies a warmer Arctic,  on land especially over thinner sea ice.  Still implying the bulge of winter moved Northwards in several locations.  Over the oceans and virtually on every part of the continents,  whereas winter of old still exists but for much shorter time periods.  On the North American side,  the CTNP settling over the Eastern High Arctic give more often than not the warm winter periods of late.    However the less expansive Cold Temperature Vortice centers on each continents make for dramatic weather changes,  which make the news because these weather events are usually out of time and place.
