| 摘 要： | 珠穆朗玛峰东侧东绒布冰川积累区的降水主要是由印度夏季风环流带来的.根据东绒布冰芯记录恢复的净积累量与印度中北部和印度半岛东部地区的夏季风降水量具有基本一致的周期, 三者有着较好的相关性, 因此可以通过冰芯净积累量来反映更长时间序列印度某些地区夏季风降水量的变化趋势.东绒布冰芯净积累量的相对变化幅度大于印度夏季风降水量的变化, 表明高海拔地区的降水比低海拔地区具有更高的敏感性.

| Abstract: | The precipitation in the accumulation zone of the East Rongbuk Glacier on the east slope of the Mount Qomolangma is mostly brought on by Indian summer monsoon. It is found that there is a coincidence in period between the net accumulation rate derived from the East Rongbuk ice core and the summer monsoon rainfall of North Central India and East Peninsular India, together with a fine correlation between them. Thus, the series of Indian summer monsoon rainfall of the regions mentioned above could be extrapolated from the net accumulation rate of the East Rongbuk Glacier. Variation of the net accumulation rate of the East Rongbuk Glacier is appreciably earlier than that of the Indian summer monsoon rainfall, and the changing magnitude of the former is larger than that of the later, which means sensitivity of precipitation increase with elevation. |
