摘要

气候变化会改变积雪的演变,进而影响雪崩的可能性和洪水风险。在系统地阐明气候--积雪--雪灾的动态变化链方面,缺乏有关高山主要积雪特征的系统观测数据仍然是一项科学挑战。这限制了我们对雪相关灾害风险预测的理解并带来了挑战。因此,本研究基于天山昆塞河谷 1967 年至 2021 年的地面观测资料,分析了气温和降雪量的变化以及雪堆的物理特征。结果表明,雪季气温每十年显著上升 0.32 °C(p < 0.01),同时极端降雪事件增多。从 1967 年到 2021 年,积雪覆盖期每十年缩短了 4.77 d(p < 0.01),其特点是积雪开始时间推迟,融雪时间提前。同时,平均积雪深度和最大积雪深度增加,峰值雪水当量增加,从而表明极少雪或丰雪年的频率增加。春季积雪温度梯度较低,融雪日期提前,导致融雪洪水和湿滑坡提前发生。随着这些事件风险的增加,它们对农田、道路交通、水电基础设施和其他一些人类活动构成了更大的威胁。因此,这些洞察力对于提供重要信息至关重要,可以加深我们对气候变化对积雪特征影响的理解,并改进与积雪有关的灾害预防和缓解的管理策略。

Snowpack variations and their hazardous effects under climate warming in the central Tianshan Mountains

Climate change alters snowpack evolution, which in turn influences the likelihood of snow avalanches and flood risks. The lack of systemic observational data on key snow characteristics in high mountains remains a scientific challenge in terms of systematically elucidating the dynamic chain of variations in climate–snowpack–snow disasters. This restricts our understanding and poses challenges in the prediction of snow-related disaster risks. As such, this study analysed the variations of temperature and snowfall and the physical characteristics of snowpacks based on ground-based observations from the Kunse River Valley situated in the Tianshan Mountains from 1967 to 2021. The results reveal that the temperature increased significantly by 0.32 °C per decade (p < 0.01) during the snow season, along with more extreme snowfall events. The snow-cover duration was observed to have been shortened by 4.77 d per decade (p < 0.01) from 1967 to 2021, which is characterised by later snow-cover onset and earlier snowmelt. Concurrently, average and maximum snow depths increased along with an increase in peak snow water equivalent, thus indicating a higher frequency of extremely scarce or abundant snow years. The low snowpack temperature gradient and earlier snowmelt dates in spring lead to earlier occurrences of snowmelt floods and wet avalanches. As the risks of these events increase, they pose greater threats to farmlands, road transportation, water–electricity infrastructure and several other human activities. Therefore, these insights are critical for providing vital information that can deepen our understanding of the impact of climate change on snowpack characteristics and improve management strategies for snow-related disaster prevention and mitigation.
