Turbulent Cascade at 1 AU in High Cross-Helicity Flows

摘要: Analysis of the scaling mixed third moments velocity and magnetic fluctuations in solar wind plasma, energy cascade rates derived from scaling, reveal a strong dependence on amount cross-field correlation between field fluctuations. When is greater than about 75%, rate outward-propagating (majority) component, total cross-helicity are surprisingly negative. This indicates back transfer small to large scales within inertial range dominant component. It clear that acts reinforce dominance component may explain, part, persistent observations correlations have been defining aspect physics for almost 40 years.
