Multifractals in the solar wind

Multifractals have been observed in the solar wind in several contexts. The velocity fluctuations observed by Voyager 2 near 8 AU have the structure of intermittent turbulence which has multifractal scaling symmetry. The velocity fluctuations in corotating streams at 1 AU and near 6 AU also have multifractal structure, and the structure evolves significantly between 1 AU and 6 AU. Multifractal scaling has also been observed in the magnetic field strength, density and temperature in recurrent streams at 1 AN and in large-scale fluctuations the magnetic field strength at 25 AU.
