| 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 phenomena, such as interplanetary coronal mass ejections (ICMEs), co-rotating interaction regions (CIRs), shocks and also their mixed structures, have been reported and studied. Now, it is well accepted that these large-scale interplanetary structures are the main causes of the geospace environmental disturbances, which can affect infrastructure systems and technologies in space and on Earth, including satellite and airline operations, communication networks, navigations systems, and the electric power grid. Most discussions about the large-scale interplanetary phenomena focus on the following issues: (1) The solar or interplanetary sources of these phenomena; (2) The propagation and interaction between these phenomena, such as ICME-ICME interaction, shock-ICME interaction, ICME-CIR interaction and so on; (3) The properties of different interplanetary structures and their variations with solar cycle; (4) The space weather effect of these phenomena, especially their geoeffectiveness. This session will exhibit and discuss the recent advances of these issues, especially the recent progress on the interaction between multiple interplanetary phenomena and the differences in their properties in the 24th and previous solar cycles. |
