| Zusammenfassung |
| The climatic variables are supposed to be the influential factors for the summer accumulation
type glaciers in the Nyainqêntanglha Range, Tibetan Plateau. There are certainly
unique regional climate regimes within this area during different seasons. In the
summer season, the prevailing regional climate is controlled by a plenty of moisture
transported by the warm summer monsoons, while it is getting colder and drier by
the westerlies from the inland of Eurasia in the winter season. The impact of the
resultant local hydro-thermal condition fluctuation on the the glacier dynamics is still
not well understood. In this study, the seasonal patterns of glacier behaviors are
estimated in terms of glacier surface displacements under a certain climatological
state (2006-2009). The glacier surface displacements are derived from Landsat
imageries by using the feature tracking method. The land surface temperatures and
precipitations are selected as the representative parameters of the regional climate
in the Nyainqêntanglha Range. According to the tendency analysis, the apparent
annual cycle of precipitation and land surface temperature are recognized. At the
same time, the diurnal change of land surface temperature (>0°C mostly in the
daytime, |
