Polar Jet Stream

[William]

The jet stream looks rather odd. If you look at this site, Over past months, the jet steam is only strong across the Atlantic.  It is almost gone across Russia and is nothing to write home about across the Pacific.  What is different.  Could it be that large block of ice that sits on top of Greenland.  With solar radiation being reflected back into space and hence not warming the atmosphere from below and with melting ice, cooling the atmosphere in its region, Greenland will be an area of prevailing sinking air as the air radiated heat into space and cools.  This will power the Polar Hadley Cell and where it meets the Ferral cell, we will have a jet stream.  If the Arctic becomes ice free will we see a jet stream that circles Greenland or will the jet stream completely disappear.
