SH33B:
Waves, Turbulence, and Dissipation in Solar and Heliospheric Plasma Structures Posters

Submit an Abstract to this Session



Session ID#: 26221

Session Description:
Remote-sensing and in-situ observations of solar coronal and heliospheric plasma provide ample evidence of waves and dissipation in MHD and kinetic regimes in turbulent solar and heliospheric plasma. The waves are detected in a wide range of scales, from global coronal waves, to kinetic scales in the magnetized inhomogeneous plasma structures. Evidence for turbulence and cascade is found from fluid to kinetic dissipation regimes. Laboratory experiments provide an important platform to study these waves in the various regimes in laminar and turbulent plasma, providing input for plasma wave theory development. Numerical models of the MHD and plasma kinetic waves and turbulence provide the critical connections between the observations, laboratory experiment, and theory. The goal of the session is to bridge the gaps between observers, experimentalist, and modelers of waves, turbulence and dissipation processes in solar and heliospheric plasma. Contributions based on recent observations and modeling results are especially welcome.
