Query: Strong Anisotropic MHD Turbulence with Cross Helicity   This paper proposes a new phenomenology for strong incompressible MHD
turbulence with nonzero cross helicity. This phenomenology is then developed
into a quantitative Fokker-Planck model that describes the time evolution of
the anisotropic power spectra of the fluctuations propagating parallel and
anti-parallel to the background magnetic field. It is found that in steady
state the power spectra of the magnetic field and total energy are steeper than
a Kolmogorov spectrum and become increasingly steep as C/E increases, where C
is the cross helicity and E is the fluctuation energy. Increasing C with fixed
E increases the time required for energy to cascade to smaller scales, reduces
the cascade power, and increases the anisotropy of the small-scale
fluctuations. The implications of these results for the solar wind and solar
corona are discussed in some detail.
