説明
Snowfall in Japan is predicted to decrease under global climate change. Such a decrease will cause the decrease of water resources stored as snow cover. Using a decadal global climate change prediction we estimated the water equivalents of snowfall in 20 major Japanese catchments over 100 years. The annual water equivalents of snowfall will decrease in all catchments in the future.<BR>In Hokkaido, the annual decreae of water equivalent of snowfall is small. On the Pacific side of central Japan, the rate is intermediate, but the decrease in the amount of water is small. In western Japan, the rate is large, but the decreased of amount of water is small. Thus a small change of outflow is expected in those areas. Among all catchments studied, the most affected is the Shinano River on the Sea of Japan side of central Japan. The decrease is intermediate almost half of the present amount. But the annual volume of water equivalent of snowfall decreases by 4.6×109m3 100 years from now. The results are similar for other catchments in the area. Comparing to the annual precipitation, the decrease of annual water equivalent of snowfall is expected to be large enough to change the characteristics of outflow in those catchments.
