最近对降雪气候学的研究显示了多种趋势，但大量证据表明，降雪极端的几个指标总体上呈下降趋势。本文对最大季节性积雪深度进行的分析表明，1960/1961年冬季至2014/2015年冬季期间，该变量呈强劲的负趋势。这一结论适用于北美。在所分析的欧洲台站中，最大积雪深度也大多在减少。研究表明，北美和欧亚大陆的积雪覆盖范围和雪水当量总体呈负趋势。这些结果大部分，但不完全，与全球变暖对雪特性的影响的简单假设一致。
Recent studies of snow climatology show a mix of trends but a preponderance of evidence suggest an overall tendency toward decreases in several metrics of snow extremes. The analysis performed herein on maximum seasonal snow depth points to a robust negative trend in this variable for the period of winter 1960/1961-winter 2014/2015. This conclusion is applicable to North America. Maximum snow depth is also mostly decreasing for those European stations analyzed. Research studies show generally negative trends in snow cover extent and snow water equivalent across both North America and Eurasia. These results are mostly, but not fully, consistent with simple hypotheses for the effects of global warming on snow characteristics.
