Outline of Final Research Achievements

Extreme weather events often bring natural hazards in Japan. In particular, heavy snowfall brings great damages for inhabitants life with various disasters. Associated with recent Arctic climate changes, cold waves often attack the Far East region during winter in recent 10 years, which caused many extreme heavy snowfall events in Japan. Towards understandings of such extreme snowfall events in Japan, we developed an online auto-collecting system using weather observational network. Further, we constructed “Real-time analysis system”based on integrated data auto-collecting and analyzing system through installation of regional weather forecast models.
