SA33B:
Dynamic Interactions Between the Thermosphere and Ionosphere I

Submit an Abstract to this Session



Session ID#: 32164

Session Description:
The ionosphere and thermosphere are a dynamic, nonlinear and closely coupled system. Changes in the thermosphere, including winds, temperature and composition, have profound effects on all regions of the ionosphere, and vise versa, through chemical, momentum and energy coupling. This session focuses on recent advances in understanding the structures of the thermosphere and the ionosphere and their variations on various spatial and temporal scales under both disturbed and quiet conditions. Particular emphasis will be placed on storm-time neutral dynamic effects, electrodynamic effects, ion-neutral coupling processes that lead to various variations, as well as topside ionospheric characteristics. We will also address the upper atmosphere climatology including variations on global and local scales with solar cycle, season and local time. We welcome presentations based on in-situ and ground-based observations and data assimilation as well as numerical models.
