Tropical cyclone symmetry structure analysis method and apparatus, device, and storage medium

A tropical cyclone symmetry structure analysis apparatus, comprising:

• a first acquisition module, configured to acquire TC best track datasets in a preset time period, and acquire hourly TC locations and TC intensities based on the TC best track datasets;
• a creation module, configured to create corresponding polar coordinate systems with TC center locations as origins;
• a second acquisition module, configured to acquire hourly infrared brightness temperature data, and interpolate the infrared brightness temperature data into polar grids of the corresponding polar coordinate systems of TCs based on a temporal correspondence to obtain infrared brightness temperature polar grid data;
• a calculation module, configured to calculate convection symmetry indexes of preset inner-core regions of TCs based on the infrared brightness temperature polar grid data;
• and
• an analysis module, configured to analyze a relationship between the convection symmetry indexes and the TC intensities.
