~2019-2020 was a winter with lots of snow
~Most of it gone where it should have been remaining, that is if you look at surface temperatures and sea ice extent numbers.
~The mystery white mask of 2020 season is melting/sublimating away
The first thing we remember about 2012 sea ice melt season, was the cyclone over the Arctic Ocean on August 5. But 2012 was also a year with a more normal snow cover as opposed to 2020.
The thing about Arctic snow over ice and land is that it is spread out quite evenly by the winds which may span in the same direction for hundreds of Kilometres. 2020 spread out was more important, by about a factor of 2 compared to 2012. So you might think, 2012, the year with greatest sea ice melt on record should show more land than any other known year at an early melt season date, say June 3:
NASA EOSDIS June 3 animation for years 2012 to 2020. We see mainly Ellesmere Island and a bit of Northeast Greenland, the perineal coldest area of the Northern Hemisphere, doesn't quite matter which month you may chose. Turns out 2012, the year with less winter/spring snow precipitation, has more snow than 2020 on same June 3. This is a very significant finding. Less snow on ground means less fog or low clouds as well, 2012 shows that, unlike cloudier 2020 still in progress of melting a once thicker snow carpet. All the other June 3's from 2013 to 2019, had over all significantly more snow coverage.
