Dynamical systems theory sheds new light on compound climate extremes in Europe and Eastern North America
International audience We propose a novel approach to the study of compound extremes , grounded in dynamical systems theory. Specifically, we present the co-recurrence ratio (α), which elucidates the dependence structure between variables by quantifying their joint recurrences. This approach is appl...
