Hello,
A true greenland block that we haven't seen for a while, I was wondering what are the rough maximum temperatures you'd expect in each month of the year they happen?
To start, I'd guess 8-9 degrees in late October, 6 degrees in early-mid November, 2 degrees in Early December (was that the rough maxima in December 2010? And mainly ice days from mid December to Mid February?
I guess, the main point, I'm making through this, is at what point does extensive northern blocking become "useful". No longer what some would call a waste. That which will give a decent week long snow event, not a morning of wet snow like in late October 2008 (I think it was 08). Can anyone remember a week long snow event in Mid November from extensive northern blocking centred on Greenland?
