~ Latest sun data contradicts some of its forecast
We start with Greenland Melt extent being very quiet:
If there is a great cold atmosphere area to the West of Greenland, it would certainly affect its melt rate. It is so.
The latest sun data seems to indicate a stubborn cold zone at least 140 km wide in diameter, this because of limitations of a high sun , 20 degrees in elevation, which refraction method helps measure, covering a smaller atmospheric transect. Not long ago it was 400 km wide....
At any rate, the CAA upper atmosphere is very cold, perhaps more so than reported to ECMWF:
The sudden ECMWF drop in pressure height over the Canadian Arctic Archipelago by June 9 is the only question over this forecast, come so would result in a surprise large displacement of the coldest zone in the Northern Hemisphere. Note the projected Cyclone over the Arctic Ocean gyre area, this would be the first time in more than a month of such an image.
A switchover from steady High to Low was much forecasted in late April: http://eh2r.blogspot.com/2018/04/2018-annual-spring-summer-projection-by.html
Not quite like this ECMWF effort, we await June 9 and report back.....
