abstract = "We analyze the weak component of the localized temporal pattern
variability of 3 GHz solar burst observed by the Ondrejov
radiospectrograph. A complex, short and weak impulsive sample from
the time series was analyzed by applying a method based on the
gradient pattern analysis and discrete wavelet decomposition. By
analyzing canonical temporal variability patterns we show that the
new method can reliably characterize the phenomenological
dynamical process of short time series (N 103 measurements) as the
radio burst addressed here. In the narrowest sense, by estimating
the mutual information distance in the gradient spectra, we show
that the fluctuation pattern of the short and weak 3 GHz impulsive
solar burst, with energetic amplitudes <350 SFU, is closer to the
intermittent and strong MHD turbulent variability pattern.",
