  • Radial evolution of cross helicity at low and high latitudes in the solar wind

    Breech, Ben; Matthaeus, William H.; Minnie, J.; Oughton, Sean; Parhi, S.; Bieber, J.W.; Bavassano, B. (2005)
    We employ a turbulence transport theory to the radial evolution of the solar wind at both low and high latitudes. The theory includes cross helicity, magnetohydrodynamic (MHD) turbulence, and driving by shear and pickup ...
  • Radial evolution of cross helicity in high-latitude solar wind

    Breech, Ben; Matthaeus, William H.; Minnie, J.; Oughton, Sean; Oarhi, S.; Bieber, J.W.; Bavassano, B. (American Geophysical Union, 2005)
    We employ a turbulence transport theory to explain the high-latitude radial evolution of cross helicity, or Alfvénicity, observed by the Ulysses spacecraft. Evolution is slower than at low latitudes due to weakened shear driving.
  • Transport of cross helicity and radial evolution of alfvenicity in the solar wind

    Matthaeus, William H.; Minnie, J.; Breech, Ben; Parhi, S.; Bieber, J.W.; Oughton, Sean (American Geophysical Union, 2004)
    A transport theory including cross helicity, magnetohydrodynamic(MHD) turbulence, and driving by shear and pickup ions, is applied to the radial evolution of the solar wind. The radial decrease of cross helicity observed ...
  • Turbulence transport throughout the heliosphere

    Breech, Ben; Matthaeus, William H.; Minnie, J.; Bieber, J.W.; Oughton, Sean; Smith, Charles W.; Isenberg, P.A. (American Geophysical Union., 2007)
    We employ a turbulence transport model to compute distributions of turbulence throughout the heliosphere. The model determines the radial dependence of three (coupled) quantities that characterize interplanetary turbulence, ...
