| Outline of Final Research Achievements |
It is expected that the distribution of tropical rain in the future would change for various factors. One of those factors is the teleconnection due to the asymmetric warming between Northern and Southern Hemisphere mid-high latitudes. Previous studies have reported that the tropical rain tends to increase in the hemisphere of greater warming. The effect of ocean circulation change has not been taken into account in most studies, however. In this study, the mechanism of the teleconnection considering the ocean circulation change under the realistic future scenario was investigated. A novel point is the integration of energetic and dynamical perspectives in the interpretation of the result. Pointing the importance of ocean dynamical effect, a fundamental insight regarding the mechanism for the change in tropical rain was acquired.
