[M-IS21] Geophysical fluid dynamics-Transfield approach to geoscience

Wed. Jun 1, 2022 11:00 AM - 1:00 PM Online Poster Zoom Room (31) (Ch.31)

convener:Keita Iga(Atmosphere and Ocean Research Institute, The University of Tokyo), convener:Shigeo Yoshida(Department of Earth and Planetary Sciences, Faculty of Sciences, Kyushu University), Takatoshi Yanagisawa(Research Institute for Marine Geodynamics, Japan Agency for Marine-Earth Science and Technology), convener:Hidenori AIKI(Nagoya University), Chairperson:Keita Iga(Atmosphere and Ocean Research Institute, The University of Tokyo)

This session on geophysical fluid dynamics is open to discussions and researches on fluid phenomena in whatever fields of earth and planetary sciences, e.g., motions in the earth and planetary interior, oceans, atmospheres, volcanoes, and the ionosphere, conducted with whatever methods. Talks intending to stimulate exchange of ideas among multiple fields of researches or those identifying concepts that are commonly applicable to wide range of geophysical fluids are especially welcome.
