Variation and Distribution of Winter Snow Depth in Japan Using "Seasonal Snow Depth Index"
The "Seasonal Snow Depth Index (SSDI)" was defined for the quantitative evaluation of the distribution and variation of snow depth. SSDI distribution maps were examined for 31 winters. The snow depth distribution differed among winters. A quantitative expression of the areal distribution t...
