[P-EM16] Coupling Processes in the Atmosphere-Ionosphere System

2026年5月25日(月) 09:00 〜 10:30 304 (幕張メッセ国際会議場)

座長:Lin Charles(Department of Earth Sciences, National Cheng Kung University)、大山伸一郎(名古屋大学宇宙地球環境研究所)

The Atmosphere-Ionosphere (A-I) system forms the so-called near-Earth space. Recent rapidly expanding use of satellite constellations in low Earth orbit (LEO) drives a high demand for better understanding and accurate forecast of the global A-I system for scientific and operational purposes. This session aims to provide a forum for research advances and frontiers related to these aspects, and we invite presentations on global A-I coupling at all temporal and spatial scales. This includes but is not limited to: A-I coupling via atmospheric waves (tides, gravity waves, planetary waves) and trace gases (CO2, O3, H2O), A-I response to Space Weather events (solar flares, CMEs, CIRs), polar-equatorial, inter-hemispheric coupling via TADs/TIDs/disturbance dynamo/penetration electric field, ionospheric plasma irregularities, and ionospheric currents. Observations, theoretical studies, model simulations, data assimilation, instruments development are all highly welcome.
