Session Proposal: Three-Dimensional Magnetosphere Structure and Dynamics During Geomagnetic Storms (AGU25)

SM030
Three-Dimensional Magnetosphere Structure and Dynamics During Geomagnetic Storms

Session ID#: 247274

Session Description:
During geomagnetic storms, the magnetosphere undergoes intense interactions with the solar wind, driving energy, momentum, and mass inputs to near-Earth space. Since the Heliophysics System Observatory and recent advances in global modeling can provide a more complete picture of the coupled space weather environment than ever before, the stage is set for discovery of new physics driving the storm-time magnetosphere. Topics in this session include: (1)Structure and dynamics of the strongly driven magnetosphere during intense space weather events; (2)Strongly driven magnetic reconnection and its coupling to the larger-scale geospace environment. In-situ observations (MMS, THEMIS, Van Allen Probes, etc), remote/ground-based measurements (magnetometers, auroral all-sky imagers, radars, etc.), and numerical simulations (MHD, PIC, hybrid, etc.) are invited covering the entire terrestrial magnetosphere. We also welcome studies of solar wind drivers (coronal mass ejections, solar flares, etc) of intense storms. This session’s goal is to reveal three-dimensional connections of the dynamic storm-time magnetosphere.
