[P-EM28_29PM2] Magnetosphere-Ionosphere Coupling

Tue. Apr 29, 2014 4:15 PM - 6:00 PM 413 (4F)

Convener:*Shin'ya Nakano(The Institute of Statistical Mathematics), Yoshimasa Tanaka(National Institute of Polar Research), Tomoaki Hori(Nagoya University Solar Terrestrial Environment Laboratory Geospace Research Center), Chair:Shin'ya Nakano(The Institute of Statistical Mathematics), Yoshimasa Tanaka(National Institute of Polar Research), Tomoaki Hori(Nagoya University Solar Terrestrial Environment Laboratory Geospace Research Center)

This session targets the comprehension of phenomena stemming from magnetosphere-ionosphere coupling processes. We invite presentations which focus on understanding of multi-scale coupling in the context of compound system, investigation of coupling between high latitude and middle/low latitude, and elucidations of coupling processes from the viewpoint of elementary process. Suggestions for innovative observational/data-analysis techniques, simulation, and theory are most welcome.
