[A-CG29] Extratropical oceans and atmosphere

Fri. Jun 4, 2021 10:45 AM - 12:15 PM Ch.10 (Zoom Room 10)

convener:Toyama Katsuya(Meteorological Research Institute), Youichi Kamae(Faculty of Life and Environmental Sciences, University of Tsukuba), Shoichiro Kido(JAMSTEC Application Lab), Shion Sekizawa(Research Center for Advanced Science and Technology, University of Tokyo), Chairperson:Toyama Katsuya(Meteorological Research Institute), Shoichiro Kido(JAMSTEC Application Lab)

The extratropical ocean had been considered passive to atmospheric variability. Recent studies, however, revealed active roles of the extratropical ocean in modulating the atmosphere. The goal of this session is to deepen our understanding of the air-sea interaction in the extratropics. A wide variety of researches whose topics range from meso-scale to basin-scale interactions, and from daily to global warming timescales are welcomed. Researches on topics related to extratropical air-sea interaction, including cloud, aerosol, and ecosystem, are also welcomed.
