Waves and non-propagating modes in stratified MHD turbulence subject to a weak mean magnetic field.

The article in the Journal of Fluid Mechanics explores waves and non-propagating modes in stratified MHD turbulence with a weak mean magnetic field. It analyzes flow dynamics using linear theory and simulations for a Boussinesq fluid with unitary magnetic and thermal Prandtl numbers, identifying various motions based on Froude and Alfvén–Mach numbers. The research delves into energy distribution, cascade processes, and the impact of stratification and mean magnetic fields on kinetic, magnetic, and potential energies. The study reveals insights into the behavior of energy components, decay rates, anisotropy, and wave dynamics in stratified MHD turbulence, offering a comprehensive understanding of complex interactions in such systems.
