Summary | We did data analysis in order to examine the influence which climatic variation causes to the occurrence of avalanche, concerning the relationship between air temperature, the snowfall, snow circumstance and occurrence form of avalanche. When we see at common year ratio, we can see correlation in air temperature and snow depth when air temperature is low,snow depth becomes large. When snow depth becomes large, number of cases of the avalanche which occurs in year becomes many. But,as for clear relationship it is not seen air temperature and heavy snowfall year. |
