Abstract: Disclosed are a tropical cyclone symmetry structure analysis method and apparatus, a device, and a storage medium. TC locations and TC intensities are acquired based on TC best track datasets; polar coordinate systems are created with the TC locations as origins; hourly infrared brightness temperature data are acquired based on satellite data, and are interpolated into the corresponding polar grids to obtain infrared brightness temperature polar grid data; then convection symmetry indexes of inner-core regions of TCs are calculated based on the infrared brightness temperature polar grid data; and finally, the relationship between the convective symmetry indexes and the TC intensities is analyzed.
