instabilities and nonlinear effects play an important role in shaping the dynamics of plasma interactions by redistributing the free energy and by generating plasma waves and density irregularities. The goal of this session is to facilitate in-depth discussions
on all aspects of observation and theory of nonlinear effects and plasma instabilities in both auroral and sub-auroral geospace, to share the recent advancements, and to identify open questions in the field. Of particular interest, are multi-scale processes
that produce important effects in the magnetosphere-ionosphere-thermosphere system such as ion up-flow, plasma density irregularities, and variation of the ionospheric conductivity. Possible topics of discussion will include, but not limited to, streaming
instabilities at the auroral F region and E-region Farley$B!>(BBuneman and gradient drift instabilities. Observational results from sounding rockets, satellites, incoherent scatter radars and other ground-based instruments, as well as theoretical and numerical
works, are all welcome.</span></font></p>
