积雪分布对水文循环、气候系统、生态演化等自然过程有着深远的影响。许多研究表明，海拔、温度和降水是控制雪分布的三个主要因素。我们的研究探讨了风对雪分布的影响，发现风是控制青藏高原东北部雪分布的另一个重要因素。我们选择青藏高原东北部的祁连山作为研究区，数据包括中分辨率成像光谱仪雪区产品和天气研究与预报模型生成的大气数据集。结果表明，研究区积雪分数（FSC）面积与风速之间的相关性存在阈值海拔。在海拔3900m以上，FSC与风速呈显着负相关，在海拔3900m以下，FSC与风速呈显着正相关。我们的分析表明，3900米以上地区出现雪堆的概率较高，并且风将雪从3900米以上地区输送到海拔较低的地区。
Snow distribution has a profound impact on natural processes such as the hydrological cycle, the climate system, and ecological evolution. Many studies suggest that elevation, temperature, and precipitation are the three major factors controlling snow distribution. Our study explores the influence of wind on the snow distribution and finds that wind is another important factor controlling the snow distribution in the northeastern Tibet Plateau. We select the Qilian Mountains in the northeastern Tibetan Plateau as the study area, and the data include the moderate-resolution imaging spectroradiometer snow area product and the atmosphere dataset generated by the Weather Research and Forecasting model. The results indicate that there is a threshold elevation for the correlation between the fractional snow cover (FSC) area and the wind speed in the study area. At elevations above 3900 m, the FSC and wind speed exhibit a significant negative correlation, and at elevations below 3900 m, they exhibit a significant positive correlation. Our analyses indicate that the probability for the occurrence of snowdrifts is higher in regions above 3900 m and that the wind transports snow from regions above 3900 m to lower elevations.
