Recent Advances in ULF Wave Research: Sources and Impacts
Session ID#: 82333
Session Description:
Ultra-low frequency (ULF; 1 mHz - several Hz) waves are known to transport and couple energy throughout the geospace system. ULF waves can be driven by internal instabilities and wave-particle interactions as well as external sources such as interplanetary shocks and upstream waves in the solar wind and ion foreshock. Several spacecraft missions (e.g., THEMIS, RBSP, and MMS) and increasing coverage of ground instruments, including SuperDARN, Imagers, and ground magnetometers, have enabled significant advances in ULF wave research. For example, recent studies have shown ULF waves could affect VLF wave growth, precipitation/aurora, ring current and radiation belt processes. However, there are several outstanding questions, such as: When and where different internally and externally driven ULF waves occur? How to quantify the energy dissipation in the ionosphere related to ULF waves? This session invites papers examining the sources and impacts of ULF waves utilizing observations, theoretical arguments, and modeling efforts.
