Generalized self-similarity of intermittent plasma turbulence in space and laboratory plasmas

Zelenyi, L. M.; Savin, S. P.; Budaev, V. P.

> Statistical characteristics of plasma fluctuations in the solar wind (SW), the Earth's magnetosphere and fusion devices are reviewed. The turbulence in all these media has a complicated multiscale structure and exhibits a generalized self-similarity in an extended scale range. The anomalous transport of mass and momentum is intermittent and i…

Multipoint observations of plasma phenomena made in space by Cluster

Perri, S.; Pickett, J. S.; Sahraoui, F. +11 more

Plasmas are ubiquitous in nature, surround our local geospace environment, and permeate the universe. Plasma phenomena in space give rise to energetic particles, the aurora, solar flares and coronal mass ejections, as well as many energetic phenomena in interstellar space. Although plasmas can be studied in laboratory settings, it is often difficu…

Intermittency of magnetic field turbulence: Astrophysical applications of in-situ observations

Zelenyi, Lev M.; Artemyev, Anton V.; Bykov, Andrei M. +1 more

We briefly review some aspects of magnetic turbulence intermittency observed in space plasmas. Deviation of statistical characteristics of a system (e.g. its high statistical momenta) from the Gaussian can manifest itself as domination of rare large intensity peaks often associated with the intermittency in the system's dynamics. Thirty years ago,…
