Most glaciers in the Tibetan Plateau (TP) are experiencing dramatic retreat, which is resulting in serious environmental and ecological consequences. In addition to temperature increases, increased light-absorbing particles (LAPs) and decreased precipitation were proposed to, independently, play important roles in reducing glacier accumulation. Based on investigations of effect from an extremely low precipitation event in the TP and surrounding regions caused by La Niña from October 2020 to April 2021, a new mechanism was provided. It was shown that decreased precipitation during study period leaded to both low snow accumulation and high LAP concentrations in snow on glacier surfaces in the TP. This phenomenon will strongly enhance earlier and accelerated glacier melt in this critical region and needs to be considered in future related studies.
青藏高原（TP）上的大多数冰川都在经历急剧退缩，这导致了严重的环境和生态后果。除了温度升高外，增加的吸光粒子（LAPs）和减少的降水被认为分别在减少冰川积累方面起着重要作用。基于对 2020 年 10 月至 2021 年 4 月拉尼娜现象导致的 TP 及周边地区极低降水事件的调查，提供了一种新的机制。结果表明，研究期间降水减少导致 TP 冰川表面的雪积累量低和 LAP 浓度高。这种现象将强烈加剧该关键区域的冰川更早和加速融化，这在未来相关研究中需要考虑。
