On the ion-inertial range density power spectra in solar wind turbulence

Treumann, R.A., W. Baumjohann, and Y. Narita (2018), On the ion-inertial range density power spectra in solar wind turbulence, arXiv, 1-9, pp 9, Figures 3, Tables 2, submitted to Angeo Nov 15, 2018.

Abstract
De-magnetised ions in the ion inertial range of quasi-neutral plasmas respond
to Kolmogorov inertial range velocity turbulence power spectra via the spectrum
of its related induction electric field. Maintenance of electrical
quasi-neutrality causes deformation in the power spectral density of density
turbulence. Experimentally confirmed Kolmogorov inertial range spectra in solar
wind velocity turbulence and observations of density power spectra suggest that
the occasionally observed unexplained scale-limited ``bumps'' in the density
power spectrum are caused by this ion response. Magnetic power spectra react
passively by warranting pressure balance. While both density and magnetic
turbulence spectra in the range of ion inertial scales deviate from Kolmogorov,
the velocity turbulence preserves its Kolmogorov inertial range shape in this
process to which spectral advection turns out to be secondary.
