[ACG33-P02] The difference on the amount of snowfall of wind direction dependency in heavy snowfall area and non-heavy snowfall area
Keywords:Wind direction, Mapping, Snowfall
In this study, the top five points (Iwamizawa, Kutchan, Aomori, Shinjo, and Takada) in terms of average daily snowfall are defined as heavy snowfall areas. The results showed that the climatological wind direction, the most frequent wind direction on snowfall days, and the most likely wind direction for snowfall matched the climatological wind direction in heavy snowfall areas except for a few points. On the other hand, in non-snowfall areas, the climatological wind direction and the most likely wind direction for snowfall matched in few points. These results suggest the difference on the amount of snowfall of wind direction in heavy snowfall areas and non-heavy snowfall areas.
