ジャーナル フリーUsing the meteorological data at Takada (37°06'N 138°15'E) from March to April in 1924-1959, some heat economical problems on the techniques for the promoting snow-melt in late thawing years were studied. Main results obtained are summarized as follows :
Generally, the characteristics of heat balance at the snow surface during the thawing season indicate that the net radiation at the snow surface is larger than the total heat flux transferred from the air layer to the surface, namely, sensible and latent heat flux. Moreover, it has been found that the tendency mentioned above is obtained even during the latter thawing stage in late thawing years. However, from a consideration of the heat economical effect for the methods of promoting snow-melt in late thawing year, it seems reasonable to conclude that in the former stage of the thawing season the dusting of black powder on a snow surface is effective and in its latter stage ridging on a snow surface is effective.抄録全体を表示PDF形式でダウンロード (1340K) -

ジャーナル フリーThis is a report on the avalanche hazard area of Rebun-island, northern Hokkaido, researched on March and August in 1966.
1. There are slopes of marine terraces along the coast, on which snow-cornice and -drift are usually formed by heavy wind in winter. They often developed to snow avalanches and caused large damages.
2. From late February to early March in 1966, air temperature became very high and many ground avalanches broke out. The layer of depth hoar or of wet granular appeared to play an important part in these avalanches formation and release. Potential Magnitude (P.M.) of these avalanches were generally 3.0-4.0 and maximum 5.1.
3. The earth wind-baffle on the terrace is successful. On the longer slope, however, it is necessary to make both, the wind-baffle on the terrace and the defence structure in the sliding zone.抄録全体を表示PDF形式でダウンロード (7897K)
