Magnetotail Dipolarization and Its Effects Throughout the Magnetosphere and Ionosphere II Posters


Submit an Abstract to this Session


Session ID#: 48772

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 dipolarizations, including but not limited to the relationship between azimuthally localized (i.e., dipolarizing flux bundles, or plasma “bubbles”) and large-scale dipolarizations during substorms, how both types originate, and how they contribute to particle transport, energization, and subsequent impacts on the inner magnetosphere and ionosphere. It is imperative to bridge the outer-magnetosphere plasma sheet with the inner-magnetosphere and ionosphere, and understanding the role of dipolarizations in this coupled system could be the keystone. These questions can be addressed using in situ and/or ground-based observations as well as global and regional models and theory that incorporate magnetotail dipolarizations to examine their impacts.
