Abstract

There is growing evidence that a turbulent cascade of energy from large to small scales accounts for the dissipation of fluid energy (magnetic and velocity fluctuations) that heats the background plasma. However, much remains to be done to understand the dynamics of that cascade. We apply a structure function formalism originally derived for hydrodynamic turbulence and recently extended to include magnetohydrodynamics (MHD) to map the cascade of energy in the inertial range at 1 AU. We also examine the anisotropies associated with inertial range magnetic fluctuations in the hope of better understanding inertial- and dissipation-range dynamics.
