Abstract: The representative studies on the volcano impact on climate and their progress are reviewied systematically from two aspects: Superposed-Epoch analyses and Time-series analyses. The temporal and spatial characteristics of the climate response connected with the eruption intensity, eruption latitude, eruption season and other eruption features are shown. Some other questions related to the volcanic signal detection, such as, the volcanic index, the possible mechanism by which the volcano affects the climate, the connection between the volcano and ENSO, and so on are discussed. Finally, the research prospects in the near future are envisioned.
