: Size of tropical cyclone is often asymmetric in nature, but there is a lack of systematic, clean, and intuitive metric to specify the asymmetry which is strongly urged. A novel size asymmetry index (SAI) is therefore proposed to specify both the degree and pattern of asymmetry synthetically in this study. It is practically useful for assessing and expressing the size structure of tropical cyclone, especially for the parties in applications and research.
