Data Sources

ACE (Accumulated Cyclone Energy) is calculated at 6-hourly synoptic times (0000/0600/1200/1800 UTC) for systems with status TS, HU, or SS and wind ≥34 kt. Formula: ACE = Σ(V²max) × 10⁻⁴. Landfall category reflects the storm's intensity at the moment of landfall, not its peak intensity.
