|The complex magnetic atmosphere of the Sun supports different type of waves that are partially responsible for the mass and energy balance of the outer envelope. Among them, the internal gravity waves are thought to be generated by turbulent convection overshooting into the stably stratified medium above. However, short radiative timescales and the presence of magnetic fields restrict their propagation in the solar atmosphere. Using detailed numerical simulation, it is now possible to study gravity waves and their interaction with magnetic fields in a realistic atmosphere. In this talk, we present some of the latest results on the properties of these waves and their coupling to other magneto-atmospheric waves, highlighting their possible role in the heating of upper layers and their potential for revealing the nature of magnetized solar atmosphere.
