The phenomenon described as a coronal explosion results directly from a chromospheric explosion. These two phenomena always occur together. They are the manifestations of the impulsive phase explosions in solar flares. These explosive processes occur during and immediately after the onset of the impulsive phase of flares. A previously presented model, describing the relation between the two kinds of explosions, appears to be able to explain qualitatively, and in many cases also quantitatively, the observations relevant to these explosive processes.
