| Abstract: |
Examples of the drifting pulsating structures observed in solar dm-radio
spectra are presented. Their relationship to plasmoids in a flare current
sheet, and to their motions is explained. Then effects of the plasmoids,
especially those moving downwards and interacting with an underlying flare-loop
arcade, on a formation of flare ribbons are shown. Finally, using a 2.5-D
particle-in-cell modelling we present the spectrum of the electromagnetic
(radio) emission generated during a coalescence of the plasmoids. |
