[ChaoYUE]

Dear Colleagues,



We invite you to submit contributions to the ring current session at the
2023 AGU Fall Meeting (San Francisco, CA 11-15 December 2023).  Abstracts

The submission deadline is *August 2nd. *



*SM021. Ring Current Dynamics and Its Coupling with Other Particle
Populations*



The terrestrial ring current is comprised of ions and electrons ranging
from ~1 keV to several hundred keV and plays an important role in
regulating the energy density and magnetic field configuration of the
magnetosphere. Abrupt changes in this ion population are responsible for
global decreases in the Earth's surface magnetic field, known as
geomagnetic storms. The storm-time ring current is thus linked to harmful
space weather effects, which have motivated the study of its formation,
dynamics, decay, and coupling with other particle populations. The
instability of ring current plasma provides free energy for various waves,
which can heat or pitch-angle-scatter various other plasma populations and
result in plasma energization or loss via precipitation. We invite
presentations of theoretical studies, numerical modeling and observations
on research progress of the ring current dynamics, wave-particle
interactions, and the coupling between ring current system and particle
populations in other regimes.



Conveners: Chao Yue, Cristian Ferradas, Jacob Bortnik, Qianli Ma, Man Hua
