摘要/Abstract

摘要：

通过对2010年6月下旬于阿尔泰山蒙赫海尔汗冰川北支采集的新降雪、再冻结冰、冰雪融水、河水及雪坑样品中δ¹⁸O和δD的测定以及过量氘的计算, 利用HYSPLIT气团轨迹模型, 对研究区降水中稳定同位素的空间分布特征及水汽来源进行了初步研究. 结果表明: 新雪、再冻结冰以及河水样品中δ¹⁸O的空间分布均呈现出显著的“反高度效应”特征, 这是降雪过程中不同海拔高度水汽来源的差异造成的; 不同水体样品中均有较高的过量氘, 说明内陆再循环水汽长期对研究区的降水产生显著影响. 进一步分析表明, 影响研究区降水的内陆再循环水汽主要来自于西西伯利亚平原湿地和沼泽的蒸散发.

Abstract:

Altay Mountains are the northern periphery of the central Asian mountain system and the southern periphery of the Asian Arctic basin, which makes those mountains ideal areas for analyzing climatic records relating to both westerly jet and polar air mass. Some fresh snow, regelation ice, river water and snow pit samples from the Monh Hayrhan Glacier, Altay Mountains, were collected in June 2010. These samples of δ¹⁸O and δD were determined and their d-excess values were calculated. It is found that δ¹⁸O of all the samples from fresh snow, regelation ice and river water increase with altitude. Based on the HYSPLIT air trajectory model, the reverse tendencies to different transmission sources of moisture at different altitudes were derived. At high altitude, water vapor evaporated from the Caspian might make the biggest contribution to the snow, while at low altitude most of the water vapor might come from Arctic or West Siberia. On the other hand, the high d-excess in all samples indicate that, at least in the early summer of 2010, the re-evaporated vapor makes a great contribution to the precipitation in the study area. The mean backward trajectories show that during this time vapor sources in the study area are mainly related to the evaporation over West Siberia, one of the largest wetland in the world.
