Den anden Gruppe, der omfatter Observationerne fra
Expeditionen sidste Tur, til Beeren-Eiland, Spidsbergen
og Grønlandsisen, udviser ingen regelmæssig daglig Periode,
som det vil sees af Figuren, Pl. II. Vanddampenes Tryk,
1878, B. Den midlere Afvigelse Ira Dagsmediet (5.mm34)
er kun + 0.mm030, altsaa ikke større end MF i Gruppen
A. Kogen daglig Periode er saaledes ikke paaviselig. Vi
erindre, at den daglige Periode of Temperaturen ikke lod
sig finde af denne Gruppes Observationer.
Relativ Fugtighed.
Til Beregningen af den daglige Periode for den
relative Fugtighed ere nøjagtig de samme Observationer og
Grupper benyttede som til Vanddamptrykkets.
The other group, comprising the observations taken
on the last voyage of the Expedition, to Beeren Eiland,
Spitzbergen, and the Greenland ice, gives no regular diurnal
period, as will be seen from tbe figure in Pl. II, Force of
Vapour, 1878 B. The mean deviation from the daily mean
(5.mm34) is only + 0.mm030, accordingly not greater than MF
in group A. Hence, a diurnal period cannot be found.
As previously shown, the diurnal period of the temperature
could not be determined from the observations in this
group.
Relative Humidity.
For computing the diurnal period of the relative
humidity, precisely the same observations and groups have
been applied as for determining the force of vapour.
