SH51E:
Large-Scale Interplanetary Structures: Sources, Evolution, Space Weather Effects, and Solar Cycle Variations I

Submit an Abstract to this Session



Session ID#: 31361

Session Description:
Since 1994, WIND, ACE and other satellites have continuously recorded the in-situ solar wind magnetic field and plasma parameters near the Earth for about two solar cycles. Using these measurements, different large-scale interplanetary structures, such as interplanetary coronal mass ejections (ICMEs), stream interaction regions (SIRs), shocks and also their mixed structures, have been reported and studied. Now, it is well accepted that these structures are the main causes of geospace environmental disturbances. Most discussions about the large-scale interplanetary structures focused on the following issues: (1) their solar or interplanetary sources; (2) the propagation and interaction between these structures; (3) the evolution of interplanetary structures and their variations with solar cycle; (4) the space weather effect of these phenomena. This session will exhibit and discuss the recent advances in understanding these issues, especially the progress on the interaction between multiple interplanetary structures and the variation of these structures with solar cycles.
