Abstract: | By analysing the relationship between flares and the morphology of velocity and magnetic fields in active regions AR 5528,
AR 5629, and AR 6891, we found that initial brightening points at the earliest phase and flare ribbons at the maximum phase
are more closely related to the velocity field patterns than to magnetic field patterns. We also found that the velocity patterns
related to the flares are different from Evershed flows in the chromosphere. Finally, a model of vortex-induced reconnection
has been applied to solar flares and some preliminary results are discussed. |
