| Outline of Final Research Achievements |
Satellite imagery and weather charts show various types of cyclones over the globe, including tropical cyclones, extratropical cyclones and hybrid type of cyclones. To clarify the diversity of cyclones, we analyzed the global distribution of various types of cyclones, and then performed idealized experiments on the relationship between cyclone development and their environment using a high-resolution regional model. We have demonstrated that environmental fields can explain the cyclone development and characteristics well. We have also clarified that the subtropics is an unfavorable environment for both tropical cyclones and extratropical cyclones, and that the western parts of the oceans are favorable environments for hybrid cyclones.
