Query: Dynamics of flare processes and variety of the fine structure of solar
  radio emission over a wide frequency range of 30 - 7000 MHz   Radiobursts exibiting fine structure observed over two years during the
rising phase of Cycle 24 by the SBRS are analyzed. In five events zebra
structure, various fiber bursts and fast pulsations were observed. Events on 15
and 24 February 2011 are of the greatest interest. The polarization of radio
emission in all three cases is related to the ordinary wave mode of radio
emission.Almost all events in the microwave range contain superfine structure.
It is possible that each type of fine structure is excited by the same
mechanism, and the broad variety of events is related to the dynamics of flare
processes.
