New World Order in global atmospheric circulation is taking shape.

~The post 1998 period has a definite simple Global Circulation footprint
~Hurricane track Northeastwards  shift is understood by it. 

   Current autumn 2017 dominant circulation has 2 cold cells,  one NE Siberia,  the other usually strongest coldest Arctic Archipelago -Greenland zone.   This is what dictates a great deal of your weather if you live in the Northern Hemisphere.  In Novembers past ,  the look was different,  with the colder zones much vaster.  In response 2017 autumn was extremely warm for the largest part of North American NE coast and well further inland.  The larger question is whether these cells will remain largely similar for upcoming months. 

     The answer lies in whether we can accurately measure snow cover or not.  Current cold zones were largely built from seasonal snowfall. 

Snow is a widely misunderstood white matter, the coldest zones have naturally more snow on the ground because temperatures are almost always below 0 C. But it does not mean that where snow lies the coldest atmosphere can be.   A snow layer on top of a warmed up by summer permafrost, means that the permafrost doesn't loose so much energy to space. A closer look at the Canadian archipelago reveals far less snow on the ground than Siberia, the Archipelago always had open sea water, yet the weighted temperature of the troposphere is consistently coldest over the CAA (Canadian Arctic Archipelago).    But snowfall has largely stopped,  sublimation and compaction 

has rendered its initial snow cover thinner,  exposing the ground further during darkness only to consolidate the cooling further.

    The perfect coldest Northern Hemisphere winter would start with extensive early snowfall in autumn, then none at all for the long Arctic night followed by extensive snow precipitation April onwards. So far 2017 is following that pattern in the CAA. 

     A curious pattern shift was discovered as cited by PBS 2017 NOVA's killer hurricanes broadcast, the hurricanes use to crash consistently straight Eastwards into middle mesoamerica, now their end tracks tend to have shifted towards the Northeast. A plausible explanation would come from the Global Circulation as cited above. The remainder of the coldest 

atmosphere survives in summers in the CAA-Greenland region. This is due to great sea ice melts, much more frequent than not in the last 2 decades. Only Greenland and CAA glaciers complement the remainding dwindling September Arctic Ocean sea ice. This solidifies the center of Global Circulation to CAA-Greenland in summer and fall, the flow on NE America's coast has now been intensified, dragging everything found within,  warmer weather, Cyclones or hurricanes to move likewise.
