AbstractBased on in-situ data of Qiyi Glacier from 2010 to 2012, a daily distributed degree-day model on a 90 x 90 m grid was developed to simulate the spatial and temporal variations of the glacier mass balance, ELA, and meltwater run-off depth in the Beida River Basin from 1957 to 2012. In the model, different vertical lapse rates of temperature and precipitation gradients were used in different months and height-belts, and the influence of 'temperature jump' was also considered. The results indicated that the average annual mass balance and meltwater run-off depth of the glaciers in the Beida River Basin were -93.3 mm w.e. and 443 mm, respectively. Assuming a continuous linear trend, the ELA had risen by 505 m over 55 years. The mass balance linearly increased with the altitude in the cold season (Oct.-Apr.) and exponentially in the warm season (May-Sep.). The most possible abrupt change points of the mass balance, ELA, and meltwater run-off depth time series were all in 1992/93, as determined through the M-K test. The mass balance turned increasingly negative since then, but the ELA and meltwater run-off increased rapidly. The climate sensitivity test showed that the air temperature was a dominant factor that affected the mass balance of the continental glaciers on the basin scale, which was different from the response mechanism of maritime glaciers. When the air temperature (+1 degrees C) and precipitation (+10 %) increased simultaneously, the glacier mass loss and meltwater run- off reached 1.66 x 10(8) m(3) and 2.45 x 10(8) m(3), respectively.
