Description
A one-dimensional nonlinear dynamo model (no R-model) is
used for prediction of solar activity (Wolf numbers). The
nonlinearity includes the dynamical equation for the
magnetic helicity (the magnetic part of the alpha effect)
and algebraic nonlinearity of the total alpha effect. The
diffusion flux of magnetic helicity is taken into account.
The Gnevyshev-Ohl rule works when only the dynamic
nonlinearity is taking into account. This model reproduces
enough well the Maunder Minimum of the solar activity.
