[A-CG33] Extratropical oceans and atmosphere

Mon. May 27, 2019 3:30 PM - 5:00 PM 104 (1F)

convener:Kazuaki Nishii(Graduate School of Bioresources, Mie University), Yoshi N Sasaki(Hokkaido University), Hatsumi Nishikawa(Institute of Low Temperature Science, Hokkaido University), Shun Ohishi(Division for Land-Ocean Ecosystem Research, Institute for Space-Earth Environmental Research, Nagoya University), Chairperson:Shun Ohishi

The extratopical ocean had been considered passive to atmospheric variability. Recent studies, however, revealed some active role of the extratopical 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 mesoscale to basin-scale, and from daily to global warming are welcomed. Researches on cloud, aerosol, and ecosystem related to the extratopical air-sea interaction are also welcomed.
