Abstract:
Based on the snow depth observation data from 83 highelevation meteoro logy stations located in the QinghaiTibet Plateau during 1959-2007, the time s eries of regional snow depth increment that shows the snow depth variation with e very snowfall events has been constructed. The results show that (1) comparing w ith the monthly or annual maximum snow depth and the accumulated snow depth seri es, the new series can represent the two others, has excellent features in stati stics, and is the most stable one; and (2) the regional snow depth increment is keeping a negative phase during 1960-1966, a positive side during 1967-1998 and a negative phase again since 1999, and there is a significant jump point in the snow depth increment series that appears in 1998.
