What It Is

Real 5-minute surface wind speed at Chicago O'Hare 2023 (IEM/ASOS). 114k observations, quantized to ~1-knot steps (31 levels). Captures gusts, diurnal cycles, and frontal passages. Public domain.

Interpretation

Standard analysis sees: multifractal. The atlas finds no named structure, but the source is distinctively extreme on H² × ℝ (Thurston):depth_height_corr (-2.7z) — beyond what the standard bank predicts for it.
