Snow Disaster Forecasting System on Roads


We started to construct a snow disaster forecasting system. It is composed of three steps; firstly meteorological conditions, such as temperature, wind speed and direction, short and long wave radiation and amount of snowfall is calculated by regional weather model with a fine space resolution. Secondly the change in the property of snow cover is obtained with SNOWPACK model developed by Swiss Federal Institute for Snow and Avalanche Research. Thirdly, based on the above two steps, forecasting of the snow avalanche danger, the decrease in the visibility due to a blowing snow, and the condition of snow and ice along the road were carried out.
