| Session Description | This section will cover the response of the coupled Sun-Earth system to extreme solar events, seismic events and events at Mini-Max/23-24. Seismic events such as earthquakes and volcanoes provide the opportunity to understand upward coupling of the atmosphere through waves, and explore the possibility of using the ionosphere as a precursor of earthquake. Solar events such as CMEs provide us with valuable information about the physical processes involved in Sun-Earth system coupling primarily through magnetic reconnection, wave-particle interactions and ion-neutral collisions, which cause geomagnetic storms, auroras, electric field and current intensifications, depletion and recovery of the outer radiation belt, and thermospheric and ionospheric storms. Severe Space Weather can damage satellite systems and ground systems costing up to 1 to 2 trillion US$. Mini-Max/23-24 provides the opportunity to study the intrinsic behavior of geospace with minimum forcing from solar wind and maximum forcing from lower atmosphere which reveals prominence of sudden stratospheric warming (SSW), etc. We invite contributions of observational studies using satellite-based and/or ground-based data, modeling and theory. |
