Recent research on snow cover patterns over recent decades is reviewed for GB. Interpretation for upland areas is complicated by data availability issues. Nevertheless, two distinct features can be highlighted. Firstly, a general relationship of average yearly snow cover duration with mean temperature. This relationship is apparently non‐linear indicating that snow cover duration is especially sensitive to a defined mean temperature range. Secondly, that snow cover can be rather variable from year to year, or over multi‐year phases. This variability has been related to the frequency of synoptic‐scale atmospheric circulation patterns including the North Atlantic Oscillation. These two features are used to contextualise recent and likely future trends in snow cover. It is suggested that there may be different patterns of variability in some mountain areas compared to the adjacent lowlands. This is associated with combined effects of temperature and precipitation during exposure to different air masses. Suggestions are made for improving snow cover observations to further investigate these issues.

气候变化期间英国的积雪变化

GB综述了近几十年来对积雪模式的最新研究。数据可用性问题使对高地地区的解释变得复杂。但是，可以突出显示两个不同的功能。首先，年平均积雪持续时间与平均温度的一般关系。这种关系显然是非线性的，表明积雪持续时间对定义的平均温度范围特别敏感。其次，积雪的年数或多年阶段变化很大。这种变化与天气尺度大气环流模式（包括北大西洋涛动）的频率有关。这两个功能用于将雪灾的最新趋势和将来趋势与背景联系起来。建议与邻近的低地相比，某些山区的变异性可能不同。这与暴露于不同空气质量期间温度和降水的综合影响有关。提出了改善积雪观测的建议，以进一步调查这些问题。
