| Session Description | The highly dynamic lower part of the solar atmosphere is a rich source of magnetohydrodynamic (MHD) waves, which are excited by various plasma processes, such as granular buffeting, vortex motions, plasma jet generation, magnetic reconnection etc. These MHD waves propagate in magnetic flux concentrations which act as waveguides and connect the solar interior with the atmosphere up to the transition region and solar corona. It is now widely accepted that these waves play an important role in energy transfer between the lower and upper solar atmosphere. Nevertheless, the physical mechanisms that lead to conversion of wave energy into heat are still not clarified. Recent high-resolution ground- and space-based solar instruments, such as IBIS/DST, CRISP/SST, ROSA/DST, IRIS, Hinode, SDO, Hi-C, have provided a wealth of high spatial/temporal resolution data tracking wave propagation and damping. This provides theorists with crucial observational evidence for either supporting or refuting the proposed wave-based heating models, through indirect measurements of plasma properties such as magnetic fields, electron and mass density structure and velocity. In this session we will discuss the recently obtained results on multi-scale MHD wave mode propagation, conversion and damping obtained in the theoretical/numerical modelling and high-resolution observations. |
