                         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.",
