Seasonal Anomaly Detector
Current deviation from 30-year normals
Overview
Tracks how the current season trends relative to 30-year climate normals.
What It Does
Calculates running seasonal departure from normal. Identifies whether anomaly persistence or mean-reversion is more likely.
Why It Matters
Seasonal markets require understanding whether an ongoing anomaly will persist or revert. A hot start doesn't guarantee a hot finish.
How It Works
Pulls season-to-date data, compares to normals, identifies pattern drivers (jet stream, SSTs, blocking).
