Climatic Significance Indicated by Valley Glacier Variation in Boduizangbu on Southeast Tibetan Plateau

摘要

According to the regional climatic model and tendency, the long-term climatic change, which presents not only the climatic change, but also the regional climatic change, is discussed The glacial scale is a very important climatic indicator, which is sensitive to temperature and precipitation, and provides a foundation for the comparison of the modern and various glaciers in Bodui district. The declination value of ELA and the relevant climatic change are estimated. The results of 3 glaciers on Boduizangbo show that both modern ELA and former ELAs decrease from south to north, due to the northwards monsoon and the declining precipitation. The value of ELA in LGM is about 300-600m. If the precipitation remains constant, the summer average temperature in LGM declines by 3.7-6 K.
