Аннотация: Stratospheric volcanic eruptions have had significant impacts on the radiation budget, atmospheric and surface temperatures, precipitation and regional weather patterns, resulting in global climatic changes. The changes associated with such eruptions most commonly result in cooling during several years after events. This study aimed to reveal eco-physiological response of larch trees from northeastern Yakutia (YAK), eastern Taimyr (TAY) and Altai (ALT) regions to climatic anomalies after major volcanic eruptions CE 535, 540, 1257, 1641, 1815 and 1991 using new multiple tree-ring parameters: Tree-ring width (TRW), maximum latewood density (MXD), cell wall thicknesses (CWT), ?13C and ?18O in tree-ring cellulose. This investigation showed that TRW, CWT, MXD and ?18O chronologies recorded temperature signal, while information about precipitation and vapor pressure deficit was captured by ?13C chronologies. Sunshine duration was well recorded in ?18O from YAK and ALT. Tree-ring parameters recorded cold, wet and cloudy summer anomalies during the 6th and 13th centuries. However, significant summer anomalies after Tambora (1815) and Pinatubo (1991) eruptions were not captured by any tree-ring parameters. © 2020 JMIR Human Factors.All right reserved.
