| Zusammenfassung |
| Using the Statistical DownScaling Model (SDSM) and the
outputs from two global climate models, we investigate possible changes in
mean and extreme temperature indices and their elevation dependency over the
Yellow River source region for the two future periods 2046–2065 and
2081–2100 under the IPCC SRES A2, A1B and B1 emission scenarios. Changes in
interannual variability of mean and extreme temperature indices are also
analyzed. The validation results show that SDSM performs better in
reproducing the maximum temperature-related indices than the minimum
temperature-related indices. The projections show that by the middle and end
of the 21st century all parts of the study region may experience increases
in both mean and extreme temperature in all seasons, along with an increase
in the frequency of hot days and warm nights and with a decrease in frost
days. By the end of the 21st century, interannual variability increases in
all seasons for the frequency of hot days and warm nights and in spring for
frost days while it decreases for frost days in summer. Autumn demonstrates
pronounced elevation-dependent changes in which around six out of eight
indices show significant increasing changes with elevation. |
