Meteorology
Every year, Japan receives some of the heaviest snowfall in the world. The main reason for this is thought to be that seasonal winds from the continent pass through the relatively warm Sea of Japan, hit steep mountains and rise, forming clouds. However, the amount of snowfall at each location strongly depends on the local topography of the area. Snow-related accidents such as avalanches occur every year, and the influence of local topography is extremely important in determining whether such accidents occur. However, the topography is complex, and point observations such as AMeDAS are only made at intervals of several tens of kilometers, making it impossible to capture local fluctuations. Therefore, in this special project, we will focus on local fluctuations in snowfall, conduct observations at multiple locations within a range that correspond to the same AMeDAS location, and analyze the data obtained. As a result, we understand local variations in snowfall.
