在保加利亚山区的16个气候站对1931-2000年期间的积雪变化（最大深度和积雪持续时间）进行了调查。在这一时期，山区气候的特点是普遍变暖和冬季降水减少。然而，没有证据表明积雪深度或积雪持续时间有类似的大规模减少：一些站点的积雪明显减少，一些站点没有变化，而另一些站点则明显增加。需要进一步的分析来了解积雪对气候变化的不同反应的原因。
An investigation of change in snow cover (maximum depth and snow cover duration) over the 1931-2000 period was carried out at sixteen climate stations located in mountainous areas of Bulgaria. The mountain climate has been characterized by widespread warming and decreased winter precipitation over this period. However, there was no evidence of similar large-scale reductions in snow depth or snow cover duration: some sites showed significant decreases in snow cover, some no change, while others showed significant increases. Further analysis is required to understand the reasons for the varied response of snow cover to a changing climate.
