The response of annual minimum temperature on the eastern central Tibetan Plateau to large volcanic eruptions over the period 1380–2014 CE

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