Abstract
From the stand-point of snow research and investigation, a series research of field works was carried out to get informations on snow cover in the south of Hokuriku District.
Observations were carried out at the two places; one is the Gosyogahara Village in the north of Katsuyama City and the other is the Fukui Base-ball ground in Fukui City, Fukui Prefecture from Dec. 17, 1967 to Apr. 20, 1968.
Analysing results of observations in compliance with the following consideration;
variations of physical characters fixed on the snow cover were assumed to be expressed as follows,
V=Vl+Vs+Vp
where
V : variations of physical characters annexed to the snow cover.
Vl : variations continued systematically throught the winter.
Vs : variations depended on weather conditions.
Vp : random variations depended on the point where the snow samplings were made.
an existence of the variation Vl could be observed from the results (see fig. 46) of the observations through the winter.
Prior to a quantitative treatment of the variation Vl, individual measurement, Vs and Vp, will be essential for a right understanding of the long period variation.
The writer wishes to take above mentioned measurements in this coming winter season.
