Yes I would like to concur with these thoughts re Greenland. Very much like northerlies to the uk. In FI they look like clean beauties but as higher resolution kicks in the short waves kick in and it all becomes much messier in general most of the time. The same happens here and I have seen it much myself. Unsurprising given the locale around Iceland-Greenland is practically an area of semi permanent low pressure. I always think for most things nothing is impossible and hence with the weather especially there will always be times a clean shift of the PV towards Siberia will occurr but as the time nears, it can't help be favoured that bit more, a chunk of PV reimagining stubborn near Greenland and effectively, bottling the cold air or the true interest up north still.
