| Outline of Final Research Achievements |
By using datasets of climate projections and global warming predictions in Coupled Model Intercomparison Project (CMIP) and further advanced climate simulations, we further our understanding of "Climate variability and predictability in the extratropics." Focusing on interannual to decadal variability of extreme weather events such as heavy daily rainfall potentials over East Asia, we demonstrated the potential predictability based on signal-to-noise ratio in large-ensemble simulations of an atmospheric model, and verified the actual predictability and prediction skills in initialized climate predictions. We also clarified the governing mechanisms of remote effects of global climate variability that can control statistics of extreme weather events and their decadal modulations, using observational data, reanalysis data and numerical simulations.
