雅鲁藏布江流域出山口（巴昔卡）逐月径流模拟数据（2018-2019）

第三极经历了冰川加速退缩的过程，特别是在喜马拉雅东部，这与21世纪初季风降水量的减少相吻合。在雅鲁藏布江下游冰川融水径流较大，降水丰富，二者对地表径流的贡献及影响却未知。大量海洋冰川消失在多大程度上减缓雅鲁藏布江流域降水径流的减少是不清楚的。借助于多圈层水文模型WEB-DHM和墨脱境内获取的第一手水文气象观测数据开展了雅鲁藏布江流域水文过程的模拟研究，巴昔卡为出山口点，该点的经纬度信息为95.53E，28.10N。The Third Pole has witnessed accelerated glacier retreat, particularly in the eastern Himalayas, which coincides with the decline in monsoon precipitation since the early 21st century. In the lower reaches of the Yarlung Zangbo River, glacial meltwater runoff is substantial and precipitation is abundant, yet their respective contributions to and impacts on surface runoff remain unclear. It remains unknown to what extent the disappearance of large marine glaciers mitigates the reduction in precipitation-runoff in the Yarlung Zangbo River Basin. Leveraging the multi-sphere hydrological model WEB-DHM and first-hand hydrometeorological observation data collected in Medog County, we conducted a simulation study of hydrological processes in the Yarlung Zangbo River Basin, with Baxika as the outlet point whose geographic coordinates are 95.53°E and 28.10°N.
