M. Dikpati et Ar. Choudhuri, ON THE OUT-OF-PHASE APPEARANCE OF LARGE-SCALE DIFFUSE MAGNETIC-FIELD OF THE SUN WITH RESPECT TO SUNSPOTS, Astrophysics and space science, 243(1), 1996, pp. 169-172
We assume the large-scale diffuse magnetic field of the Sun to origina
te from the poloidal component of a dynamo operating at the base of th
e convection zone, whereas the sunspots are due to the toroidal compon
ent. The evolution of the poloidal component is studied to model the p
oleward migration of the diffuse field seen on the solar surface and t
he polar reversal at the time of sunspot maxima (Dikpati and Choudhuri
1994, 1995).
