Abstract: | The behavior of dynamo waves in a two-layer medium is investigated in terms of the Parker dynamo model. The solar cycle duration
is shown to depend on the ratio of turbulent diffusivities in the layers. Meridional circulation has been incorporated into
the Parker system. An increase in the intensity of meridional flows is shown to decelerate the propagation of dynamo waves.
The minimum of solar magnetic activity can occur not only in the case of intense meridional circulation in both layers but
also when a difference in physical characteristics arises between the layers and the meridional flows are moderate. |
