利用平流层分辨率GCM进行了灵敏度实验，其中平流层的平均状态和变率已经改变。结果表明，这对北半球冬季地面气候的平均值和变率有显著影响。特别指出的是，平流层对地面北极涛动的持续有很强的贡献，滞后10-25天。这证实了平流层对地表气候的重要性，这是最近在再分析数据集中审查北极涛动的研究所推断的。
A sensitivity experiment has been performed with a stratosphere‐resolving GCM where the mean state and variability of the stratosphere have been altered. It is shown that this has a significant effect on the mean and variability of wintertime northern hemisphere surface climate. In particular it is shown that the stratosphere strongly contributes to the persistence of the surface Arctic Oscillation at lags of 10–25 days. This confirms the importance of the stratosphere on surface climate that has been inferred by recent studies examining the Arctic Oscillation in reanalysis datasets.
