Abstract
Two examples of clouds of narrowband dm-spikes, observed by the Ondrej ov radiospectrograph in the 1-2 GHz frequency range, are analyzed. Aft er transformation of the frequency scales to distances in the solar at mosphere, the power spectra analysis of size scales reveals a spectral index of-5/3, resembling that of Kolmogorov spectra of turbulent casc ades. The narrowband dm-spikes are interpreted as radio emission from electrons accelerated in MHD cascading waves, probably generated in pl asma outflows from magnetic field reconnection.
