What It Is

Lorenz-96 atmospheric-dynamics ODE with N=4 variables and high forcing F=16 (required for chaos at small N). Observable is x_0(t). Attractor fractal dim ~2.5-3.

Interpretation

Standard analysis sees: smooth / autocorrelated; red spectrum (low-frequency / 1-over-f power); low-complexity (predictable, not noise-like); time-irreversible (slow rise, sharp collapse); volatility-clustering (bursty). The atlas finds no named structure, but the source is distinctively extreme on Bispectrum:coupling_frequency_centroid (-3.0z) — beyond what the standard bank predicts for it.
