Geophysical Research Letters, 32(6), L06103.https://hdl.handle.net/10289/8578We 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.application/pdfen© 2005 the American Geophysical Unionsolar windJournal Article10.1029/2004gl022321
