Scopes:

In the present Earth system, various kinds of time-space fluctuations in interdisciplinary physical phenomena have been observed within the multiple spheres (atmosphere-ocean-cryosphere-geosphere) in polar region. An understanding of the mechanism and activities for these interdisciplinary phenomena has significance to evaluate the accurate responses of the polar systems involving global warming, which is currently progressing at the whole Earth's surface.
Taking these issues into account, the conveners would like to invite many contributions to this special session, which treat recent scientific achievements of various physical phenomena associated with interactions between multiple spheres, including a part of ionosphere. On the basis of new information from several kinds of long-term phenomena, such as the variations in strength of wave amplitudes as well as their frequency responses, a polar amplification of global warming in high latitude is chiefly focused.
