Dm-spikes and their relation to other flare phenomena in October 14, 1983 event

Using the observations in H-alpha and radio frequencies between 169 MHz and 37 GHz on October 14, 1983 a two-ribbon flare was analyzed. A coherent picture of the event is given using the standard topology for two-ribbon flares and describing the dm-spikes as manifestations of electron acceleration in a reconnection process (with a stationary shock wave). The drifting chains of these spikes are explained by the movement of this ''stationary'' shock wave. It is shown that the behavior with time of the number density of the spikes is in agreement with that of the 37 GHz flux and hence the same population of accelerated electrons that gave rise to the spikes also produced the 37 GHz radiation.
