Outline of Final Research Achievements

Snow cover changes in high latitude regions due to global warming enhance a local warming through the reduction of surface albedo. This can affect atmospheric circulation. To investigate an effect of the snow cover changes on East Asia climate, snow-albedo feedback in northern Eurasia simulated by Earth system model (ESM) has been analyzed, and sensitivity experiments by climate model have been conducted.
In the future projections by the ESM, snow amount in northern Eurasia tends to decrease in fall, winter, and spring. However, in Siberia during winter, snow amount increases. Particularly decrease in snow during spring is dominant rather than that in fall and winter, and enhance local warming substantially through reduction of surface albedo. In addtion to the snow cover changes, our analysis suggests future change in vegetation may be a factor in the reduction of local surface albedo.
