Solar Atmospheric Dynamics

Abstract

This review focuses on acoustic oscillations n the solar at- mosphere.There s much debate on photospheric p stons to chromo- spher c oscillations,on the penetration height of acoustic shocks,and on the r contr but on to chromospheric heat ng,w th new nput coming from space observations and from numer cal simulations.Less progress s made in identifying wave modes or wave heating n magnetic structures,but it seems that umbral ?ashes are ripe for understanding.
