摘要: We have extended the recent analyses of magnetohydrodynamic third moments as they relate to turbulent energy cascade in solar wind consider effects large-scale shear flows. Moments from a large set Advanced Composition Explorer data been taken, and chosen intervals are characterized by rate change speed. Mean dissipation rates obtained accordance with predictions homogeneous shear-driven turbulence. Agreement is best made for rarefaction where speed decreasing time. For intervals, we find that increase increasing magnitude shear-induced fluctuation anisotropy consistent relatively small amount.
