Vv. Pipin et Ll. Kichatinov, The solar dynamo and integrated irradiance variations in the course of the11-year cycle, ASTRON REP, 44(11), 2000, pp. 771-779
The effect of the large-scale magnetic fields generated by the solar dynamo
on the radiation flux issuing from the convection zone is studied. A gover
ning equation describing convective heat transfer is obtained in the framew
ork of mean-field magnetohydrodynamics, with account for the influence of m
agnetic fields and differential rotation on the energy budget of the convec
tion zone. The principal effects are illustrated using a one-dimensional nu
merical model. Calculations indicate that the influence of large-scale magn
etic fields can modulate the solar irradiance with a relative amplitude of
similar to0.07%. (C) 2000 MAIK "Nauka/Interperiodica".
