| Outline of Final Research Achievements |
We elucidated formation and maintenance of polar dipole simulated in a Venus general circulation model. Our high-resolution general circulation model of cloud-covered planets showed that, on a slowly rotating planet, heat fluxes due to polar waves form polar Ferrel circulation and strongly influence the global circulation structure. For explosive twin cyclones around Japan, during the merger process of the contact two cyclones, atmospheric river is formed and travels northward. This raises the efficiency of northward vapor transport south of Japan.
