The large scale features of solar activity are explained by dynamo theory in terms of mean-field magnetohydrodynamics. The helicity dependence on the magnetic field results in stabilization of the basic 22-year oscillations. The excitation of 2 modes (of dipole and quadrupole symmetry) can create nonlinear beats which may explain the secular (60 to 80 yr) modulation. The observed torsional waves can be interpreted as a back action of the dynamo waves on the differential rotation. The actual variations in solar activity are nonperiodic. There are random recurrent episodes of reduced activity like the Maunder minimum. Nonlinear dynamo models demonstrating oscillatory-chaotic behavior are discussed.
