Sea Ice survival last defence: Clouds and Cyclone friendly open water

~2013 like Gyre stall possible but 2016 July icescape not at all like 2013.

   What was hiding under the latest stable cyclone at about the Pole?   A sea water with broken pack ice mix much greater than 2013. same date 82 N 150 E.   2016 has severely less ice, its good for  cloudy Cyclones.

    April 2016 EH2r  projection called for a June July High pressure centred about the Pole,  this is happening now,  but had a real hard time establishing itself.  Since June, Atlantic and Pacific Cyclones constantly penetrated the Arctic Ocean region.  There is only one reason for that,  open water, especially mixed with broken sea ice.  There is a heat engine complex, in particular next to more consolidated ice from the Pole to North American side of Arctic, which is where the Anticyclones have a chance to last.  But the Arctic North American Arctic Quadrant sea ice has a problem,  more snow fell over it during the winter,  due to winter 2015-16 dominant circulation pattern, North Atlantic moisture shed itself there .  As you might have read,  more snow is a twin edged sword,  it protects sea ice in spring,  but also slows down accretion appreciably over the winter.   The pressure dipole now forming between Canadian Arctic Archipelago (more ice) and North of Siberia (less ice) will dominate this period for a while,  until the weaker state of sea ice, on the Canadian side of Pole, will reveal itself  after the protective snow cover vanishes completely.WD July 7, 2016
