| Outline of Final Research Achievements |
In previous theories for the atmosphere and ocean, frameworks for the dynamics of midlatitude and equatorial regions have been separated. Thus it has been impossible to continuously trace the life-cycle of wave energy from tropical to extratropical regions. This study has developed a scheme for calculating group velocity that is seamlessly diagnosable for waves at all latitudes and automatically applicable to various types of waves (Rossby, inertia-gravity, and Kelvin waves). The new scheme enables to trace the generation, circulation, and dissipation of wave energy with referring to the direction of group velocity.
