ジャーナル フリーThe author investigated the synoptic situation of heavy snow fall in Japan and obtained the following results :
i) The heavy snow fall associated with NW-Monsoon type in Japan occurs when the upper air temperature is abnormally lower and is similar with the situation of heavy snow fall in the eastern part of North America.
ii) There are ordinally the convergence of winds in the sea-side part of Hokuriku district when the NW-Monsoon is predominant.
It seems that the convergence are associated with the topographical features.
When there is cold trough in the upper air of Far East, the Cumulo-Nimbus develop and the heavy snow falls in the convergence area.抄録全体を表示PDF形式でダウンロード (1782K) -

ジャーナル フリーThis experimental observation was carried out at Takada to study the mechanism of snow melting such as the relation between the structure of snow packs or layers and the mass of snow melt. At the same time an effective method of observation was also studied.
The following interesting results were obtained.
(1) It was observed that the horizontal infiltration by snow melting was larger than the vertical. When the burst of snow melting occurred, it did not continue long time and soon became stationary again. In the experiment it was also observed that the horizontal infiltration flow ceased at the interval of 25-50 cm, but some times the interval was nearly 100 cm.
At the ceasing points, the horizontal flow then turned to the vertical infiltration or it resumed the same horizontal flow again.
(2) At the observation of snow melting on a flat land it was found that the values may be obtained by only one rain gauge. The size of which may be sufficient in 1-2 metre of caliber.
(3) As to the interval of observation, approximately 3-6 hours will be good enough on a flat land, but shorter interval will be preferable on a slope.抄録全体を表示PDF形式でダウンロード (1261K) -
