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. One of the main focuses of this group (A03-8) is the East Asian winter monsoon variability, which we find to be a manifestation of modulated seasonal evolution of planetary waves. The particular tropospheric blocking anticyclone that acts to enhance the monsoon is found to cool the Arctic stratosphere. We also demonstrate that decadal variability of the oceanic frontal zone east of Japan can not only modulate the boundary layer locally but also force a basin-scale atmospheric anomaly.
