Figure 7: Scheme summarizing the main processes at play in the North Atlantic response to volcanic eruptions.
From: Bidecadal North Atlantic ocean circulation variability controlled by timing of volcanic eruptions
Blue boxes depict oceanic processes and red boxes depict the proxies considered here. Purple arrows represent causality links together with the associated time lags in years. Dotted arrows only depict a temporal link, with no direct interaction. The green arrow represents the delayed negative feedback that triggers the reversal phase of the 20-year cycle.
