| Outline of Final Research Achievements |
This study aimed to quantified the uncertainty of climate change impact assessment in water related issues efficiently by classifying existing climate scenarios. In the first half of the research period, we focused on precipitation and classified future climate scenarios, and clarified trends among many future climate scenarios. In the latter half of the research period, the method developed was applied to large-scale ensemble data experiment results for both in the global and the Japanese region. Based on the uncertainty analysis obtained by the method, an extreme phenomenon that is important for the water related issues are evaluated with the range of future projections.
