What was Hurricane Maria pushes the jet stream North, take 2

~ A very fascinating feature of post hurricane cyclones was captured again.

2016 Hurricane Nicole turned extra tropical Cyclone peculiar feature  (explained here),  may seem ancient or distant,  given the comparatively busy 2017 season.  But there were much fewer hurricanes over a longer period,  from 2006 to 2015,  despite much warmer oceans,  in fact the conclusion that there would be less frequent but more powerful hurricanes was correct (Emmanuel),   not like Typhoons,  which are storms from a different huge Pacific Ocean playing field. 

Note the regular feature of Jet stream (drawn green)  on this CMC Oct 7, 2017 1800 UTC surface analysis chart.   It contours the Southern part of Cyclones,  this is a normal for the Polar jet stream ,  except for where a peculiar  Cyclone  near south east Greenland (ex hurricane Maria) seems to push the jet to the Northwards,  the jet contours the Cyclone very unusually.  It seems being more like an anticyclone .WD Oct7, 2017
