End of the melting season? Looks more and more like it.
Data as at 29 Aug 2020.Melt down a tad to 11.9% of the surface area of Greenland from 12.3% the day before, which is a bit above average for this date.
Precipitation well above average.
The result is a daily
SMB large gain of 3.1 GT, well above average for this date, looking close to record territory.
Cumulative
SMB gain for the year is 351 GT, merely 15 GT below the average for the year-end (31 August) of about 365 GT.
Melt may persist though reduced into early September
GFS also says that this melt will be accompanied by a procession of lows bringing a mixture of rain and snow from the south.
SMB gains - maybe some large - in prospect.This season has brought well above average melt, but very few dry days. Although melt this year looks higher overall than last year (2018-19), SMB gain is currently 180 GT greater than last year, although on 1st May 2020 SMB gain was only 10 GT above 2019.
Why? Precipitation. This year the blocking high over Greenalnd was insufficient to prevent weather systems dumping precipitation on Greenland. A very average result for the year end concealing a lot of high energy weather?

(It seems that in 2012 the melt season was characterised by the combination of high melt and very low precipitation, which led to the record low SMB gain for the year. Spectacular Greenland blocking high?).
