英文摘要	While much is known about the impacts of volcanic forcing on Northern Hemisphere (NH) climates, knowledge about Southern Hemisphere (SH) responses is still in its infancy. We examine volcanic impacts on SH temperatures following eight major late 19th and 20th century eruptions (Agung, 1963; Colima, 1913; El Chichón, 1982; Pinatubo, 1991; Krakatau, 1883; Quizapu, 1932; Santa Maria, 1902; Tarawera, 1886). Coupled Model Intercomparison Project, Phase 5 (CMIP5) historical simulations are used to analyze near-surface land temperatures. We demonstrate that four of the eight major eruptions (Krakatau, Santa Maria, Agung, and Pinatubo) significantly lowered mean SH temperatures; these tropical eruptions emitted at least 20 Tg of SO2 into the stratosphere. SH responses typically lagged NH temperature cooling responses by 1–2 months, excluding Pinatubo. Responses differ spatially and temporally with each eruption, highlighting the importance of investigating events individually. Overall, we observe relatively strong (between −0.19°C and −0.36°C) austral autumn/winter SH cooling. ©2020. American Geophysical Union. All Rights Reserved.
