the meteorological office in Reykjavík. The meteorological
station is on Stórhöfði in Heimaey (h. 122 m, lat. 63° 24'
N, long. 20° 17' W).
Table 2 is taken from Mölholm Hansen (Hansen, 1930),
and shows the climate of the Westmann Islands for the
years 1872—1906 (h. 8 m, lat. 63° 26' N, long. 20° 18' W).
Table 3 shows the climate at Lækjamót in N-Iceland
and covers the years 1926—1929, as shown in the weather
reports of the meteorological office in Reykjavík (h. 43
m, lat. 65° 25' N, long. 20° 31' W).
Table 4 shows the climate in the Faroe Islands as shown
in ’Tublikationer fra det danske meteorologiske Institut,
1922—1933”. The rainfall shows the average figure of
the average rainfall at the stations Myggenæs (h. 110 m,
lat. 62° 6' N, long. 7° 40' W), Höjvig (h. 10 m, lat. 62°
3' N, long. 6° 45' W) and Sand (h. 13 m, lat. 61° 51' N,
long. 6° 49' W) during the years 1922—1931, save that
for Myggenæs the year 1932 was sustituted for 1922. The
average temperature, with the absolute maximum and
minimum temperatures and the number of snowy days
are taken from Myggenæs. The force of the wind was
measured at Höjvig at 8 a. m. in the years 1926—1929.
Figures of meteorological observations in the West-
mann Islands are available from two observation stations
and two periods, and some differences are to be seen,
especially of course in the temperature, owing to the
difference in the height of the observation stations, i. e.
122 — 8 = 114 m, and the difference in temperature
in 0.7 ° C.
The tables also show that the average temperature of
the sea in the years 1872—1906 was 6.9°, but for 1921—
1930 7.8°, in other words the difference in the temperature
of the sea at these two periods is 0.9°. It also appears
that the temperature of the sea is on the whole higher
than that of the air and this even in the summer months,
except July. This shows clearly what a tremendous in-
fluence the Gulf Stream has on the winter temperature of
