| dc.description.abstract | Repeated Grand Minima revealed by proxies of solar activity suggest that the Sun alternates between two stable states, a quiescent and an active one. If the intrinsic noise of the solar dynamo allows for a frequent switching between these stable states, a tiny periodic modulation of the corresponding transition probabilities can be greatly amplified – a phenomenon known as stochastic resonance. It is well-known that Babcock-Leighton-type dynamo models can be reduced to a stochastic iterative map model capable of capturing the essential low-frequency features of the solar dynamo mechanism. In such a simplified framework, we give numerical evidence that a tiny tidal modulation of the minimal magnetic field required for flux-tube buoyancy is greatly amplified by the dynamo, provided that it operates close enough to a critical bifurcation point. Inference with more refined dynamo models is required to test this “criticality hypothesis”. | de_CH |
