| Summary: | <p>Despite several studies on decadal-scale solar influence on
climate, a systematic analysis of the Sun's contribution to decadal surface
climate predictability is still missing. Here, we disentangle the
solar-cycle-induced climate response from internal variability and from
other external forcings such as greenhouse gases. We utilize two 10-member
ensemble simulations with a state-of-the-art chemistry–climate model, to
date a unique dataset in chemistry–climate modeling. Using these model
simulations, we quantify the potential predictability related to the solar
cycle and demonstrate that the detectability of the solar influence on
surface climate depends on the magnitude of the solar cycle. Further, we
show that a strong solar cycle forcing organizes and synchronizes the
decadal-scale component of the North Atlantic Oscillation, the dominant mode
of climate variability in the North Atlantic region.</p> |
