Abstract

The relationship between gas-dynamic processes and particle acceleration is illustrated using three examples. For the flare of July 6, 2006, observations show that explosive evaporation of the chromosphere occurs in the pulse phase. In addition, the coronal mass emission (CME) related to this flare reflects the primary energy release. In the strong limb flare of July 14, 2005, the CME observed in the external layers of the corona seems to be a consequence of repeated energy releases and plasma emissions. Apparently, this is indicated by the additional emission in the decimeter range, which is typical of posteruptive processes. An example of a weak flare during the decay phase of the strong event of April 15, 2001, was also accompanied by a decimeter burst.
