The solar cycle : parity interactions and amplitude modulation

  title={The solar cycle : parity interactions and amplitude modulation},
  author={Steven M. Tobias},
Two mechanisms for producing modulation of the basic eleven year solar cycle are included in a nonlinear αω dynamo model. In the first, the modulation of the toroidal magnetic field energy is associated with large changes in the parity (symmetry) of solutions. The second mechanism introduces modulation of the magnetic field by including the action of the Lorentz force in driving macrodynamic velocity perturbations (the Malkus-Proctor mechanism) in the limit of small magnetic Prandtl numbers… CONTINUE READING
