Power and spectral index anisotropy of the entire inertial range of turbulence in the fast solar wind
Power and spectral index anisotropy of the entire inertial range of turbulence in the fast solar wind
We measure the power and spectral index anisotropy of high speed solar wind turbulence from scales larger than the outer scale down to the ion gyroscale, thus covering the entire inertial range. We show that the power and spectral indices at the outer scale of turbulence are approximately isotropic. The …
