The final post-analysis value for Typhoon No. 4 differs from the value released live. The live release reflects the storm’s operational position data during its active period. After Typhoon No. 4 ended, the China Meteorological Administration reanalysis incorporated more complete observations to produce best-track data, which is generally used for academic research and historical rankings. Data sources: CMA Tropical Cyclone Best Track Dataset (compiled via IBTrACS v04r01); wind speed converted from knots to m/s and rounded.
