Outline of Final Research Achievements

Over the last five years, the “Hot Spot Project” on extratropical air-sea interaction has conducted comprehensive research, providing a number of pieces of evidence that extratropical ocean, especially the warm Kuroshio and its Extension east of Japan and an associated frontal sea-surface temperature gradient with the cool Oyashio, can actively influence the overlying atmosphere. In addition, the continental marginal seas, i.e., the Okhotsk, Sea of Japan, Yellow and East China Seas, are also found to influence the overlying atmosphere. These oceanic influences are through a variety of phenomena on various spatio-temporal scales, including cloud/precipitation systems and basin-scale flows.
