Session ID#: 50320

Session Description:
Excitation of plasma waves, instabilities, and turbulence have been manifested in remote and in-situ space observations on a wide range of spatio-temporal scales. A few examples of these phenomena include Alfven and kink waves in chromospheric and coronal structures, acoustic modes in photosphere and convection zone, turbulence and kinetic waves in the solar wind. Laboratory experiments have made vital contributions in developing models that can accurately predict propagation and damping of plasma waves and instabilities. Improvements and validation of theoretical/numerical models for solar plasma can help us fully utilize diagnostic capabilities of these waves and understand their role in energy transport. This session invites participation of space observers, modelers, and plasma physicists working in this broad area of research. Contributions based on recent (SDO, Hinode, IRIS, WIND, ACE, Helios, Cluster, and MMS) and planning for next generation observational facilities (DKIST, EST, Solar-Orbiter, and Parker Solar Probe) are especially welcome.
