~The atmosphere of NE USA was much colder than Northern Greenland and Ellesmere
~CTNP cell moved South met a passing Northeast'ner
CMC February 9 2017 surface analysis 1800 UTC, markings 700 mb and 250 mb 1200 UTC. CTNP's of North America, 2 Vortices of the Arctic Polar Vortex, are new and old, the new one just started over Northern Alaska and Yukon,. The few days in age older one now hovering over Hudson Bay with coldest spot Ungava Quebec, this one moved South affecting the jet stream in blue, having a collision course with an Atlantic cyclone winter storm Niko, Most people way South over there in NE US had several recent Cyclones pass by, but none gave this massive snow cover because of mild winter. But just one of the Polar Vortex vortices, caused havoc. I've marked in red 250 mb wind directions making a nice vortex around Hudson Bay, in green is the 700 mb -20 C isotherm. Northern Ellesmere 700 mb temperature was -15 C, 700 mb is close to 600 mb a pressure height close to where the average temperature of the entire troposphere may be found. For those unfamiliar with Ellesmere Island Canada North Coast, it is 2520 nautical miles straight Northwards from NYC, traditionally where usually the coldest temperatures in the Northern hemisphere may be found at this time of the year. As written on my previous article smaller vortices of the Polar Vortex tend to move quite rapidly, therefore this winter pretty much represents many coming years cold seasons, warmer but sudden much colder harsh snowstorms, and back to mild winter, back and forth unstable weather.
