SM44A:
Dipolarization Throughout the Magnetotail and Its Effects on the Inner Magnetosphere II

Submit an Abstract to this Session



Session ID#: 33013

Session Description:
Dipolarization is part of a dynamic process that accelerates and transports particles throughout the magnetotail plasma sheet and inner magnetosphere, and is an important component of plasma convection in Earth’s magnetosphere. Dipolarization is also related to wave generation, which can further accelerate and/or scatter particles. This session focuses on understanding the effects of dipolarization, such as how azimuthally localized dipolarization (i.e., dipolarizing flux bundles, or plasma “bubbles”) connects to the large-scale dipolarization during substorms, how both types originate, and how small- and large-scale dipolarization impacts the inner magnetosphere. How does outer-magnetosphere plasma sheet physics couple to inner magnetospheric dynamics, and vice versa? This question is at a frontier of magnetospheric research and understanding the role of dipolarizations in this coupled system is key. This session solicits studies of magnetospheric dipolarization and its effects on the plasma sheet and inner-magnetosphere using in situ observations, ground-based observations, and/or models and theory.
