Abstract
We perform numerical simulations to characterize the transition from strong to weak magnetohydrodynamic (MHD) turbulence for freely decaying incompressible flows in presence of a uniform magnetic field B0- Due to reduction of energetic transfers along B0, the flow anisotropy, as measured for example by Shebalin angles, increases together with B0 intensity. At high B0, ratios of Alfvén to nonlinear turnover timescales stay below unity allowing for an Iroshnikov-Kraichnan description of anisotropic flows.
