Abstract: Active regions and sunspots, which sometimes produce massive eruptions, are formed as a consequence of magnetic flux emergence from the deep solar convection zone. To this end, we have performed a series of flux emergence simulations using the radiative magnetohydrodynamics code R2D2, which allows us to study the close interplay between deep, large-scale convection and rising magnetic flux systems in a single computational box. This presentation reviews how large-scale turbulent convection perverts the magnetic flux, produces complex active regions in the photosphere, and supplies magnetic helicity and magnetic energy to the upper atmospheres.
