The stations are very few and their measurements hardly
quite trustworthy in all cases. The measurement of precipi-
tation in solid form during winter is especially difficult on
account of the strong winds, that almost invariably accompany
the falling of snow. The amounts ought therefore most pro-
bably to be a good deal higher, in the north especially. From
the central highland no data are available at all, but the
increasing height of the firnlimit from the coast to that region
makes it probable that the minimum of precipitation is to be
found there, especially north of Vatnajökull in shelter from
rainbearing air-currents both from south and west.
The maximum of precipitation runs along the southern
slopes of the ice-covered mountainblocks near the southcoast.
The greatest annual precipitation, 2175 mm., has the station
Vík near the southern side of Mýrdalsjökull.
As no systematical measurements of thewater discharge of the
Icelandic rivers have as yet been made, itisatpresentimpossible
to compare the run-off with the assumed precipitation normals.
