摘要: We present results of convective turbulent dynamo simulations including a coronal layer in spherical wedge. find an equatorward migration the radial and azimuthal fields similar to behavior sunspots during solar cycle. The field coexist with spoke-like differential rotation anti-solar (clockwise) meridional circulation. Even though extends over whole convection zone, mechanism causing this is not yet fully understood.
