In the hydrological year 2022/2023,the glaciers in the Qilian Mountains experienced unprecedented mass *** glacier-wide mass balance was-1,188 mm w.e.,in contrast to-350 mm of average mass balance since 1990 over the Bailanghe Glacier No.12 in the middle of Qilian *** temperature during 2022–2023 reached the highest value ever recorded,second only to 2022,while at the same time the precipitation amount was less compared to other year since 2000,which together led to the strongest glacier mass loss during 2022–*** atmospheric circulation analysis shows that the high temperature in the Qilian Mountains in 2023 was jointly caused by the Arctic air mass and East Asian monsoon.

Due to global warming, glaciers on the Tibetan Plateau(TP) are experiencing widespread shrinkage; however, the mechanisms controlling glacier variations across the TP are still rather unclear, especially on the northeastern TP. In this study, a physically based, distributed surface-energy and mass-balance model was used to simulate glacier mass balance forced by meteorological data. The model was applied to Laohugou No. 12 Glacier, western Qilian Mountains, China, during2010~2012. The simulated albedo and mass balance were validated and calibrated by in situ measurements. The simulated annual glacier-wide mass balances were-385 mm water equivalent(w.e.) in 2010/2011 and-232 mm w.e. in 2011/2012,respectively. The mean equilibrium-line altitude(ELA) was 5,015 m a.s.l., during 2010~2012, which ascended by 215 m compared to that in the 1970 s. The mean accumulation area ratio(AAR) was 39% during the two years. Climatic-sensitivity experiments indicated that the change of glacier mass balance resulting from a 1.5 °C increase in air temperature could be offset by a 30% increase in annual precipitation. The glacier mass balance varied linearly with precipitation, at a rate of130 mm w.e. per 10% change in total precipitation.

The net accumulation record of ice core is one of the most reliable indicators for reconstructing precipitation changes in high mountains. A 20.12 m ice core was drilled in 2006 from the accumulation zone of Laohugou Glacier No.12 in the northeastern Tibetan Plateau, China. We obtained the precipitation from the ice core net accumulation during 1960-2006, and found out the relationship between Laohugou ice core record and other data from surrounding sites of the northeastern Tibetan Plateau. Results showed that during 1960-2006, the precipitation in the high mountains showed firstly an increasing trend, while during 1980 to 2006 it showed an obvious decreasing trend. Reconstructed precipitation change in the Laohugou glacier basin was consistent with the measured data from the nearby weather stations in the lower mountain of Subei, and the correlation coefficient was 0.619 （P〈0.001）. However, the precipitation in the high mountain was about 3 times more than that of the lower mountain. The precipitation in Laohugou Glacier No.12 of the western Qilian Mountains corresponded well to the net accumulation of Dunde ice core during the same period, tree-ring reconstructed precipitation, the measured data of multiple meteorological stations in the northeastern Tibetan Plateau, and also the changes of adjacent PDSI drought index. Precipitation changes of the Laohugou glacier basin and other sites of the northeastern Tibetan Plateau had significantly positive correlation with ENSO, which implied that the regional alpine precipitation change was very likely to be influenced by ENSO.

冰川温度是表征冰川物理属性和响应气候变化的关键指标。2010年7月至2011年11月在祁连山老虎沟12号冰川积累区(5040 m)、多年平衡线处(4900 m)和消融区(4550 m)开展了活动层(22 m深,1 m间隔)冰温连续观测。2011年10月在冰川积累区4971 m处钻得165 m深孔获取了115 m深层冰温廓线。研究发现:三个区域活动层下界的深度均在约17 m处,多年平衡线处冰温最低(-7.4℃),消融区次之(-3.68℃),积累区活动层下界冰温最高(-2.74℃)且波动最为持续,可能主要与常年积雪覆盖有关。冰温年波动随深度增加均逐渐降低,对气温变化的响应周期亦逐渐增大。与其他冰川最低温相比,老虎沟12号冰川冰温对气候变化响应敏感,过去50年来受全球变暖影响冰温显著增加。积累区深孔冰温显示50 m深度之下冰温呈线性上升,垂直增温率为0.033℃·m^-1,据此推测其底部冰温为0.02℃,主要与底部应变热有关。

冰芯所记录的积累量是恢复高山区过去降水变化最可靠的指标。2006年在青藏高原东北缘祁连山老虎沟12号冰川粒雪盆海拔5040 m处钻取了的一支20.12 m的冰芯,利用其年积累量估算了1960-2006年期间的冰川区降水量,结合2010年实测资料,分析了这一时期降水变化特征并研究其与周边其他地区降水变化的关系。结果表明,在过去50年中,高山冰川区降水量表现出先增加后减少的趋势。在1960-1980年,降水量表现出明显增加趋势,1980-2006年表现出明显减小趋势。重建的冰川区降水量变化与临近低海拔区的肃北气象站降水变化有很好的一致性,二者相关系数为0.619(P<0.001),而量级上高山区是低山区的约3倍。祁连山老虎沟冰川区降水与周边的敦德冰芯同期的累积量、树轮重建降水、青藏高原东北部多个气象站点的实测降水,以及临近区域格点PDSI干旱指数变化对应较好。此外,近50年来祁连山老虎沟冰川区及毗邻的青藏高原东北部地区降水变化与ENSO呈正相关关系明显,反映了该地区高海拔大气降水变化很可能受ENSO的影响。

本文基于评估和订正后的高亚洲精细再分析数据集(HAR v2),利用COSIMA单点能量−物质平衡模型系统分析了祁连山老虎沟12号冰川消融区4550 m自动气象站处2012年物质和能量交换过程及其对气候变化的响应特征,并在此基础上首次重建了1991—2020年能量和物质平衡序列。研究结果表明:①HAR v2数据集在研究区具有良好的适用性,由此驱动的COSIMA模型显示2012年冰川消融区模拟年累积物质平衡为-2333 mm w.e.。净短波辐射是冰川消融的主要能量来源(90.1%),净长波辐射是能量的主要输出项(58.6%);②该冰川物质平衡对降水变化总体保持线性响应,但对气温变化的响应表现出非对称性和非线性响应特征;③近30 a冰川表面能量收入项中净短波辐射、感热通量多年平均占比分别为89.2%、10.8%,而能量支出项中净长波辐射、消融耗热、潜热通量和地热通量多年平均占比依次为58.6%、26.5%、12.4%和2.5%。该冰川消融区长期处于物质高亏损状态,多年平均消融量为−2392 mm w.e.。在云量以及相对湿度、风速等其它气象因素影响下,净短波辐射的变幅大大超过感热通量、净长波辐射和潜热通量等能量项的变幅是该冰川消融强、弱年形成的主要原因。此外,固态降水也是制约冰川物质平衡的重要因素。
