Scientific paper

Turbulent convection of the Sun demonstrates very complicated dynamics, which is often associated with different scales of self-organization. In particular, vortex tube structures have been identified initially in numerical simulations and then in high-resolution observations. We present new results of 3D radiative MHD simulations of a top layer of the convective zone that reveal the important role of turbulent vortex tubes in various solar processes: acoustic waves excitation, convective downdrafts, spontaneous formation of stable magnetic structures and others. We consider various aspects of the vortex tubes dynamics, including their formation, identification, physical characteristics, and links to phenomena observed in the quiet Sun and magnetic regions. We compare the simulation results with observational data from SDO/HMI, Hinode and large ground-based telescope.
