On the comparison of filament chirality and axial magnetic fields deduced from a flux transport model

In this paper a comparison between the observed chirality of filaments and the axial component of magnetic field obtained from a flux transport model is carried out. The flux transport model considers the effects of differential rotation, meridional flows and diffusion acting on both photospheric and coronal fields. From this it is determined whether the hemispheric pattern of filaments originates from flux transport effects. The filaments considered formed over a four month period during CR 1724-1727 when there was little or no flux emergence. Along with the comparison a detailed analysis of a special case in which dipped inverse polarity field lines formed within a quadrapolar region during CR1724 is also described.
