Abstract: | Using the snow cover fraction (SNC) output from eight WCRP CMIP3 climate models under SRES A2, A1B, and B1 scenarios,
the future trend of SNC over East Asia is analyzed. Results show that SNC is likely to decrease in East Asia, with the fastest
decrease in spring, then winter and autumn, and the slowest in summer. In spring and winter the SNC decreases faster in
the Qinghai-Xizang Plateau than in northern East Asia, while in autumn there is little difference between them. Among the
various scenarios, SRES A2 has the largest decrease trend, then A1B, and B1 has the smallest trend. The decrease in SNC is
mainly caused by the changes in surface air temperature and snowfall, which contribute differently to the SNC trends in different
regions and seasons. |
