| Zusammenfassung |
| We develop a theoretical model of an inertial-range energy spectrum for homogeneous whistler turbulence.
The theory is a generalization of the Iroshnikov-Kraichnan concept of the
inertial-range magnetohydrodynamic turbulence. In the model the dispersion relation is used to derive
scaling laws for whistler waves at highly oblique propagation with respect to the mean magnetic field.
The model predicts an energy spectrum for such whistler waves with a spectral index −2.5
in the perpendicular component of the wave vector and thus provides an interpretation about
recent discoveries of the second inertial-range of magnetic energy spectra at high frequencies in the solar wind. |
