Descripción
Sumario:Spectral distribution of the cross helicity in the solar wind was investigated. It was found that the space plasma turbulence is distributed anisotropically in space relative to magnetic field direction. The cross helicity was found to enter a magnetohydrodynamic description on equal footing with the energy. The rotational symmetry of the cross helicity was examined. It was found that the cross helicity is associated more or less equally with all angular components of the fluctuations.
