A key prediction of turbulence theories is frame-invariance, and in magnetohydrodynamic (MHD) turbulence, axisymmetry of fluctuations with respect to the background magnetic field. Paradoxically the power in fluctuations in the turbulent solar wind are observed to be ordered with respect to the bulk macroscopic flow as well as the background magne…

Mirror Mode Expansion in Planetary Magnetosheaths: Bohm-like Diffusion
DOI: 10.1103/PhysRevLett.107.245005 Bibcode: 2011PhRvL.107x5005H

Tsurutani, Bruce T.; Hasegawa, Akira

Observed scale sizes of mirror modes in planetary magnetosheaths tend to be equal or larger than those that correspond to the maximum growth rate of the mirror instability: 9 ρp (proton gyroradius). These phenomena can be accounted for by introducing a diffusion process (Bohm) that shifts the spectra to lower wave numbers as the mode co…
