Key Findings
Modern Event-Frequency Bootstrap Results
Bootstrap-corrected early-vs-modern event frequencies. Wide original CSVs are preserved in the package.
Compound Hazards
Compound class bootstrap table
Scoring weights
Terrain Roles
The terrain story is asymmetric: ridges buffer VPD much more than Tmax, while valleys amplify cold far more than heat.
Frozen Proxy Validation
Zone-level frozen proxy validation against ASOS weather-code confirmation. ASOS exposure mismatch is a built-in caveat, especially for ridge crests.
Corrected Teleconnections
Raw ENSO dominance collapsed after month-standardization and detrending. Robust corrected signals concentrate around PDO, AMO-like variability, AO, and NAO.
Mahantango / WE-38 Linkage
The WE-38 watershed provides nearby watershed-scale process evidence. The transect provides terrain-climate structure. Together they form a nested, multi-scale evidence chain.
