Data and Code for: Forward-Only Temporal-Coherence Occupancy Regimes in Atlantic Tropical Cyclone Intensity Evolution (1851–2024)

Minimal public reproducibility package for the manuscript: “Forward-Only Temporal-Coherence Occupancy Regimes in Atlantic Tropical Cyclone Intensity Evolution (1851–2024)” This archive contains a forward-only VMAX-based occupancy diagnostic evaluated on Atlantic HURDAT2 tropical cyclone best-track records. The implementation uses causal rolling means over multiple advisory-window lengths (3, 5, and 9 advisories), directional-agreement activation logic, and replay-constrained occupancy computation using only current and prior observations. Included materials: minimal HURDAT2 preprocessing utilities, occupancy diagnostic implementation, small example/mock inputs, reproducibility metadata, validation reports, manifest/checksum integrity files. The archive is intentionally minimal and scoped specifically to the reproducibility requirements of the manuscript analyses. RI is treated as an outcome layer for stratification and regime comparison; this package is not an operational RI forecast model.
