  • Anisotropic scaling of magnetohydrodynamic turbulence

    Horbury, Timothy S.; Forman, Miriam A.; Oughton, Sean (American Physical Society, 2008)
    We present a quantitative estimate of the anisotropic power and scaling of magnetic field fluctuations in inertial range magnetohydrodynamic turbulence, using a novel wavelet technique applied to spacecraft measurements ...
  • Anisotropic three-dimensional MHD turbulence

    Matthaeus, William H.; Ghosh, Sanjoy; Oughton, Sean; Roberts, D. Aaron (1996)
    Direct spectral method simulation of the three-dimensional magnetohydrodynamics (MHD) equations is used to explore anisotropy that develops from initially isotropic fluctuations as a consequence of a uniform applied magnetic ...
  • Conditions for sustainment of magnetohydrodynamic turbulence driven by Alfvén waves

    Dmitruk, Pablo; Matthaeus, William H.; Milano, L. J.; Oughton, Sean (American Institute of Physics, 2001)
    In a number of space and astrophysical plasmas,turbulence is driven by the supply of wave energy. In the context of incompressible magnetohydrodynamics (MHD) there are basic physical reasons, associated with conservation ...
  • Coronal heating by magnetohydrodynamic turbulence driven by reflected low-frequency waves

    Matthaeus, William H.; Zank, Gary P.; Oughton, Sean; Mullan, D. J.; Dmitruk, Pablo (IOP PUBLISHING LTD, 1999)
    A candidate mechanism for the heating of the solar corona in open field line regions is described. The interaction of Alfvén waves, generated in the photosphere or chromosphere, with their reflections and the subsequent ...
  • Coronal heating distribution due to low-frequency, wave-driven turbulence

    Dmitruk, Pablo; Matthaeus, William H.; Milano, L. J.; Oughton, Sean; Zank, Gary P.; Mullan, D. J. (University of Chicago Press, 2002)
    The heating of the lower solar corona is examined using numerical simulations and theoretical models of magnetohydrodynamic turbulence in open magnetic regions. A turbulent energy cascade to small length scales perpendicular ...

  • Maxwell's Equations on a 10-Dimensional Manifold with local Symmetry so(2,3)

    Crump, William Peter (University of Waikato, 2012)
    The Hawthorn model is built upon the idea that the Lie algebra so(2, 3) is a more natural description of the local structure of spacetime than the Poincar´e Lie algebra. This model uses a 10-dimensional spacetime referred ...
  • A Review of the Dynamics and Oscillations of the Atmosphere

    Ross, Joseph (University of Waikato, 2012)
    The atmosphere is a complex, dynamic system and the weather depends on its state. There are many different phenomena that affect the state of the atmosphere - some only involve the atmosphere, others involve the interaction ...
