Outline of Final Research Achievements

The horizontal distribution of snow amount has not been understood because of a lack of observation in the mountainous areas in Central Japan. This research observed snow cover at Tateyama-Kurobe Alpine Route and conducted numerical simulations using high-resolution regional climate model. The numerical simulations with different grid-spacings showed that the numerical model with 2 km grid-spacing were required to accurately simulate snow cover over the Japanese Northern Alps. The high-resolution numerical simulations and analysis of synoptic-scale atmospheric circulation elucidated the mechanism of small snow amounts in 2015/16 winter. The 17-years numerical simulation also clarify the altitudinal dependency of annual variation of snow cover around the Japanese Northern Alps. Analyzing future climate projections conducted by the regional climate model, total snowfall will decrease, while extremely heavy snowfall can be enhanced in the Japanese Northern Alps due to global warming.
