我们分析了冬季和夏季气候信号后，15个主要的热带火山爆发在过去的半个千年的基础上，欧洲的多代理重建。在喷发后的第一和第二年，我们发现显着的大陆规模的夏季冷却和中欧有点干燥的条件。在北方半球的冬季，火山强迫诱导大气环流响应，显着遵循一个积极的NAO状态与一个显着的整体温暖的异常和潮湿的条件在北方欧洲。我们的研究结果与GCM研究以及观测研究相比，主要涵盖了较短的仪器周期，因此包括一组有限的主要喷发。
We analyse the winter and summer climatic signal following 15 major tropical volcanic eruptions over the last half millennium based on multi-proxy reconstructions for Europe. During the first and second post-eruption years we find significant continental scale summer cooling and somewhat drier conditions over Central Europe. In the Northern Hemispheric winter the volcanic forcing induces an atmospheric circulation response that significantly follows a positive NAO state connected with a significant overall warm anomaly and wetter conditions over Northern Europe. Our findings compare well with GCM studies as well as observational studies, which mainly cover the substantially shorter instrumental period and thus include a limited set of major eruptions.
