Some characteristics of temporal profiles detected by burst trigger of the AVS-F apparatus onboard the CORONAS-F satellite are discussed. Two classes of short events with a duration of some milliseconds were observed. The first class of short events is very similar to y-events appearing in the Earth's atmosphere (TGF). The second class of short events is connected with the detector persistence. We made an effort to separate such events by the use of the fractal analysis. We discuss the conditions at which the time series may be considered as statistically self-affine ones. The conditions of applicability of the cell mechanism of definition of fractal dimension of the temporal profiles detected by the AVS-F apparatus in a flare mode are considered and the results of definition of a fractal dimension of these time series are presented. In all, 100 flare temporal profiles are studied and three TGF-similar events are selected. One of the events is observed in the immediate vicinity of the centre of the tropical cyclone Beni, which confirms its interpretation as TGF.
