We consider three MHD modes (Alvén, slow, and fast), including viscous and resistive dissipation, cases with external magnetic fields of varying strength and direction (spherical and spiral waves), and the Hall effect and some instances of nonlinear effects. Applications to the solar atmosphere and wind show that MHD waves play a major role in energy and mass balance in the solar system. Here we concentrate on magneto-atmospheric waves and the Sun.
