Observing and modelling plasma flows and MHD waves in the lower solar atmosphere
Description: The lower solar atmosphere is characterised by complex plasma dynamics, presenting various phenomena linked to MHD wave excitation, energy transport and heating. The dynamics and activity of the solar atmosphere are associated with the magnetic fields, which are inherently coupled to photospheric and chromospheric flows. Therefore, realistic models for the lower atmosphere are essential to adequately describe the complex interaction of magnetic fields and plasma flows that can e.g., generate MHD waves, launch jets of plasma, form vortex motions, cause instabilities and generate turbulence. With the latest generation of ground-based observations and the development of new space-based observatories, we are entering an era of unprecedented solar monitoring. This will help significantly in improving MHD models used for understanding the interactions between magnetic fields and flows in the photosphere and chromosphere. Our session will be dedicated to exploring current and future high-resolution investigations. Thereby, we intend to provide an excellent platform for rich discussions between renowned scientists, early career and PhD researchers working on the synergy between high-resolution observations and HPC simulations describing the various phenomena that can be observed in the smallest scale magnetic structures of the lower atmosphere.
