The coupling mechanism of the glacial and the climatic changes of the southeast Nyanqingtanggula Mountain on the Qinghai-Tibetan Plateau, China

The spatial distribution and change of the mountain glaciers in midlatitude areas are quite sensitive to climatic response. According to the well-preserved old glacial relics formed during the LGM in the southeast Nyanqintanggula Mountain on the Tibetan Plateau and the relationship between the glacier variety and the climate under the modern conditions, this paper suggests that the coupling mechanisms of glaciers and climatic factors in the regional climatic fluctuation are mainly influenced by the Indian Monsoon, and a response model of the relationship between the glaciers and the climatic factors through the statistics methods. The result shows that the summer temperature during LGM in this region is 5degC lower than the modern temperature, and the precipitation near the snow line is 66% of the modern precipitation
