Wave and Plasma Structures in the Subauroral Geospace
Session ID#: 75625
Session Description:
Observations from the ground and satellites suggest that the plasmapause plays a crucial role in the transport and conversion of mass, energy and momentum in the subauroral geospace. In particular, it converts the kinetic energy of earthbound plasma jets moving from the reconnection region in the magnetotail into a large-scale electric field driving subauroral flows known as SAID and SAPS. This process is inherently unstable and associates with various plasma instabilities generating plasma turbulence, as well as small-scale magnetic field-aligned currents and ULF/FLF electromagnetic waves in the plasmasphere and ionosphere. The focus of this session are ground-based and satellite observations, theory and simulations of multiscale wave and plasma structures occurring near the plasmapause in the Earth’s magnetosphere and ionosphere. Presentations of observations, theory, and numerical results using/connecting/explaining observations from several ground and space platforms (e.g., data from DMSP, Cluster, THEMIS, MMS, and Van Allen Probe satellites) are particularly encouraged.
