Scope The extratropical ocean has been considered to vary only in responding passively to remote forcing from tropical climate variability via atmospheric teleconnection. Recent studies have revealed, however, some active roles of the extratropical ocean in the climate system, including a tendency for a strong warm current as the Gulf Stream and Kuroshio to organize a convective cloud band and a tendency for an oceanic frontal zone with tight meridional temperature gradient to yield pronounced thermal anomalies through its latitudinal displacement and thereby change heat and moisture supplies into the atmosphere. In recognition of the climatic importance of these oceanic impacts, the conveners of this session organized a nation-wide project on the extratropical air-sea interaction in 2010. The project focuses on midlatitude oceanic frontal zones where heat and moisture supplies into the atmosphere are geographically concentrated and thus intense along warm currents, referring to them as "hot spots" in the climate system. Setting its primary target region over the western North Pacific, where the most pronounced "hot spot" over the globe forms under the East Asian monsoon, the project is developing comprehensive research activity, including air-sea interactions over the marginal seas (East China Sea, Seas of Japan and Okhotsk). The aim of this international session is to review and update rapidly expanding knowledge of particular aspects of air-sea interactions that characterize the climatic "hot spots" and to discuss future directions of extratropical climate study with invited overseas speakers. Contributing oral and poster presentations are welcomed.
Notes 1) Please be sure to complete your oral presentation within 12 minutes so as to allow 3 minutes for discussion. 2) Every poster presenter is asked to make a 3-min. oral presentation at the end of the morning or afternoon session for introducing his/her poster (max. 3 slides).
