Synchronization in mean field dynamo models

Synchronization is a fundamental phenomenon in nonlinear dynamical systems. In my presentation I will refer to essential features of synchronized systems with focus on a kinematic dynamo model driven by two counter-rotating disks including weak periodic perturbations. Similar concepts can be used to explain the behavior of triadic resonances in a precession driven flow, which may be seen as a precursor for the transition into a turbulent regime found at a critical precession ratio in the DRESDYN water experiment. Finally, I show the connection to the synchronized solar dynamo model presented by Frank Stefani, where the magnetic field frequencies are determined by the tidal forces caused by planets surrounding the sun.
