A Numerical Study of Hydromagnetics of the Solar Cycle

[摘要]  A numerical study of non-axisymmetric hydromagnetic model of the solar cycle is described. The medium is assumed incompressible and confined between two differentially rotating spherical shells, then the basic equations of hydromagnetic are integrated. It is shown that magnetic activity develops near the heliographic latitude 30°. However, it is found that the present model leads eventually to axisymmetric flows and magnetic fields in the presence of viscosity and magnetic diffusivity due to the axisymmetric boundary conditions. The improvements of the model and the direction of future investigations are discussed.
