Abstract :
Our one dimensional numerical simulations describe the evolution of large amplitude Alfvèn waves excited in the lower corona as they travel upwards guided by the open magnetic field lines of a gravitationally stratified solar coronal hole. When the waves reach the region where β ≪ 1 they develop into magnetohydrodynamic (MHD) shocks. The shock waves seem to produce sufficient heat fluxes to be important contributors to the heating of the solar corona.
