https://www.dmi.dk/en/groenland/maalinger/greenland-ice-sheet-surface-mass-budget/https://nsidc.org/greenland-today/While I have been wittering on about low precipitation and the only melting being a bit of sublimation I totally missed that there was a melting event for two or three days about a week ago. And yesterday 1% of Greenland had melting! And melting may still be happening today!!
The first two images below illustrate the depth of my dumbness.
mea culpa, mea maxima culpa.
Meanwhile, back to precipitation The script has changed a tiny bit:-
After the Sept / Oct large precipitation, Greenland surface mass gain still continues very much on the average to low side. GFS seems to have changed its mind - very low precipitation for the next 10 days.
I will continue to cling to "my theory that belongs to me", i.e. that the decline in precipitation that started in November coincides with the onset and continuance of La Nina conditions and this is not a coincidence.
The utterly average precipitation since October during this 2017-18 winter is the real oddity given the extreme abnormal events elsewhere in the Northern Hemisphere. An example of when nothing happening is as significant as something happening? It is totally boring, but at least we now have the prospect of melting to speculate about.
