Volcanic eruptions have a significant impact on global temperature; their consequences are of particular interest in regions that are especially sensitive to climate change, like the Tibetan Plateau. In this study, we develop a temperature-sensitive tree-ring-width standard chronology covering the period 1348–2014 CE using Qilian juniper (Sabina przewalskii (Kom.)) samples collected from the Animaqin Mountains on the Tibetan Plateau. We reconstruct the annual (prior August to current July) mean minimum temperature (T_min) since 1380 CE and show that our reconstruction explains 58 % of the variance during the 1960–2014 calibration period. Our results demonstrate that in 77.8 % of cases in which a volcanic eruption with a Volcanic Explosivity Index of 5 or greater occurs, temperature decreases in the year of or the year following the eruption. The results of the superposed epoch analysis also indicate that there is a high probability that the T_min decreases for 2 years after a large volcanic eruption, especially when such eruptions occur in the Northern Hemisphere.

1380-2014年间青藏高原东部中部年最低温度对大火山喷发的响应

火山喷发对全球温度有重大影响；在对气候变化特别敏感的地区，例如青藏高原，其后果尤为令人关注。在这项研究中，我们使用从青藏高原阿尼玛琴山采集的祁连杜松（Sabina przewalskii（Kom。））样品，开发了一个对温度敏感的年轮宽标准年表，涵盖了1348-2014年。我们重建年度（前八月到当前月）平均最低气温（牛逼_分钟）（自1380年起），表明我们的重建解释了1960-2014年校准期间58％的方差。我们的结果表明，在77.8％的火山爆发指数为5或更高的火山喷发中，温度在喷发的年份或年份降低。叠加时代分析的结果还表明，在一次大的火山喷发后，T _min在两年内下降的可能性很高，尤其是当这种喷发发生在北半球时。
