| Outline of Final Research Achievements |
This study firstly developed a method and definitions which quantitatively detects the features of baroclinic waves observed in the experiments with a differentially heated rotating fluid annulus. The Particle Image Velocimetry (PIV) provided the high-resolution digital data of the surface flow in the experiments. Our quantitative definitions using the calculated kinetic energy captured the surface flow pattern in the experiments. Future work will involve the development of the experiments to form the tropical cyclones, and our method could be applied to provide new and useful insights into the inner core structure of tropical cyclones.
