| Abstract: | Based on the observed data of snow cover days of 232 weather stations from 1951 to 2004 and the daily snow depth data of SMMR and SSM/I during the period from 1980 to 2004 in West China,classification and decadal variations of snow cover days are analyzed.The results from the two kinds of data are compared as well.It is found that North Xinjiang,Tianshan Mountains and the east of Tibetan Plateau,with over 60 snow cover days,are the regions of stable seasonal snow cover.Regions without snow cover include the... |
