Past, Present, and Future Variability of Atlantic Meridional Overturning Circulation in CMIP6 Ensembles
Abstract. The Atlantic Meridional Overturning Circulation (AMOC) is a key component of the climate system, exhibiting strong variability across daily to millennial timescales and significantly influen...

[3/4] ANOVA allows to study the explanatory power of qualitative factors (here, different scenarios, models, ensemble members and time steps) on a quantitative variable (here, AMOC intensity). We can then track the main effect of each factor on variability and the interaction effects between them.

[2/4] Key findings: (1) Three successive regimes of variability: (i) internally-driven (1850-1990), (ii) dynamical adjustment (1990-2050), (iii) forced (2050-), (2) Differences between forcing scenarios on AMOC intensity do not emerge until 2050, (3) Internal variability decreases as AMOC declines.
