A numerical model, based on the heat balance method, was developed to simulate snowpack evolution at a given location, as a function of meteorological conditions: air-temperature, wind speed, precipitation and incident short-wave radiation.
The model takes into account three major processes, (1) the increase in the amount of snowpack by precipitation, (2) melting of the surface snow layer as a result of energy balance and (3) drainage of water from the snowpack. The model was tested with data collected at TAKADA and NAGAOKA, JAPAN. The results show the ability of the model to simulate the day-to-day changes of the snow mass with reasonable accuracy. Emphasis was placed on the characteristics unique to this and other warmer climatic regions.
