Outline of Final Research Achievements

Using high-resolution numerical models on regional and global scales, and ensemble prediction and data assimilation techniques, we clarified (1) the positive feedback process related to the rapid intensification of explosive cyclones, (2) the response of the cyclone inner system to the Kuroshio Extension warm eddies, (3) the predictability of explosive cyclogenesis and the definition of the local deepening rate, (4) the quantative estimation of orographic effects to snow storms and severe storms in northern Japan, (5) the improvement of the predictability of extraordinary high waves in the coastal regions of the Japan Sea, and (6) the long-term variability of explosive cyclogenesis in the northwestern Pacific and the possible effects of global warming.
