Schemas. Reconnection in ar–rf geometry involving (a) arcade ‘a’ and flux rope ‘r’ producing (b) a new flux rope field line ‘r’ and flare loop ‘f’. The black arrow points to an assumed reconnection site between the ‘r’ and ‘f’ field lines. (c) Processes generating radio: SPDBs, reverse and normal drift type III bursts, and a tangle of U-bursts and inverted U- bursts (Table 1); related EUV, thermal X-ray, and HXR emissions are also indicated. Schemas are not scaled in space, and the regions of electron accelerations are only illustrative.
