森林が積雪量に及ぼす影響に関する検討

Effect of forest on snow is evaluated with a proposed snow model. Wind speed and precipitation intensity and the forest condition (density of the forest and leaf) are acquired with the input data of the snow model. The snow model consists of the snowfall model and snowmelt model. The snowfall process and the amount of the snowcap are evaluated by the snowfall model. The amount of the snowmelt is estimated by the heat balance method in the snowmelt model. These models applied to various conditions (various wind speed, various LAI (Leaf Area Index)), and we can see that low wind speed deposits snow at the front of forest before higher one deposits it at the back of forest.
