Shear-Driven Transition to Isotropically Turbulent Solar Wind Outside the Alfven Critical Zone
D. Ruffolo, W. H. Matthaeus, R. Chhiber +11
Motivated by prior remote observations of a transition from striated solar coronal structures to more isotropic ``flocculated'' fluctuations, we propose that the dynamics of the in…

Magnetic field line twisting by photospheric vortices: energy storage and release
A. F. Rappazzo, M. Velli, R. B. Dahlburg +1
We investigate the dynamics of a closed corona cartesian reduced magnetohydrodynamic (MHD) model where photospheric vortices twist the coronal magnetic field lines. We consider two…
