Abstract: Smaller amounts of snow in the last 8 winters from 1986/87 to 1993/94 at Shinjo seems to be due to winter air temperature rise. Rate of temperature rise in the last century was calculated as 0.58°C/100years. The max snow depth and winter precipitation showed an inversed positive correlation with winter mean air temperatures. The max snow depth and the max winter precipitation have the max in 1936. The max snow depth and the second max precipitation which were obtained from statistically smoothed curves were found in 1940. Fluctuation in deviation of the max snow depth showed smaller values than in precipitation. The minimum of winter mean air temperature obtained from a statistically smoothed curve was found in 1940, and a rapid temperature rise was observed since around 1980. The rise in temperature might show the global warming.
