[P-EM18] [EE] Origin of Earth-affecting Coronal Mass Ejections
Wed. May 24, 2017 5:15 PM - 6:30 PM Poster Hall (International Exhibition Hall HALL7)
Coronal mass ejections (CMEs) and CME-driven shocks and sheath regions are the primary drivers of strong geo-effective response, including geomagnetic storms, sudden impulse and changes in Earth's radiation belts. This session investigates the solar, coronal and interplanetary conditions under which fast and strong CMEs form and propagate, as well as the important characteristics to understand the solar wind-magnetosphere coupling and the variations in the radiation belts during the passage of a CME. Abstracts are solicited that focus on the type of active regions and solar conditions resulting in fast and strong CMEs, the interaction of CMEs with solar wind streams and other CMEs that affect their geo-effectiveness, the characteristics of CMEs and shocks that create strong sudden impulses and changes in the flux of energetic particles in Earth's radiation belts. Contributions that cover integrated investigations combining remote observations, numerical simulations and/or in situ measurements are especially welcome.
