Abstract

The sporadic and localized interactions of magnetic coherent structures were analyzed in space plasmas which occurred due to plasma resonances. The non-Gaussian probability distribution functions of intermittent fluctuations were obtained from direct numerical simulations. The spottiness of small-scale turbulent fluctuations and nonuniformity of coarse-grained dissipation were displayed by power spectra and local intermittency measures using wavelet analysis. The dynamic renormalization group was applied to scaling properties of multiscale fluctuations.
