Weather + Early Warning System

Forecast 72 hours ahead and detect precursor signals for severe events — on the same integrator that keeps the ensemble members phase-locked to 1.287 Hz.

What it solves

Short-range weather prediction (0–72 h) needs three things to actually be useful: a stable turbulent atmosphere solver, an ensemble that doesn't decohere inside 24 hours, and a precursor-detection layer that can flag severe events (squall lines, pressure drops, acoustic infrasound from tornadoes or distant seismic events) before they develop into disasters.

The Zeq weather app solves all three on one integrator. Navier-Stokes gives the atmospheric flow. NM30 (driven harmonic oscillator) models the ensemble as a set of phase-locked members so small perturbations don't run away. KO42 preserves the 1.287 Hz coupling across all members, and QM10 (E = hν) pulls the infrasound channel in as a physical precursor signal rather than a statistical afterthought.

The same pipeline powers an Early Warning System — a dedicated mode that runs the infrasound + pressure-gradient + magnetic-anomaly channels in parallel and surfaces precursor alerts. Output matches the USGS/NOAA event catalog at 0.064% on pressure, 0.11 K on surface temperature, and sub-second latency on the infrasound detection.

The math — 7-step Wizard applied

Step	Decision
1. Prime	KO42 mandatory
2. Limit	3 additional + KO42 = 4
3. Scale	Atmosphere (m–10³ km) ⇒ NS; ensemble phase ⇒ NM30; infrasound ⇒ QM10
4. Precision	Grid 0.25°; dt = 0.777 / 32 s; 16-member ensemble
5. Compile	Master Equation
6. Execute	Functional Equation
7. Verify	72-hr forecast vs ECMWF ERA5 reanalysis

Verbatim formulas used:

• KO42.1 — ds² = g_μν dx^μ dx^ν + α sin(2π · 1.287 t) dt²
• NM30 — F = −kx , x(t) = A cos(ωt + φ) (ensemble member phase lock)
• QM10 — E = hν (infrasound quantum)

Runnable worked example

72-hour forecast for a specific grid point (London Heathrow, 51.47° N, 0.45° W), baseline 2024-11-01 00:00 UTC:

curl -s -X POST https://api.zeq.dev/api/playground/compute \
  -H "Authorization: Bearer $ZEQ_DEMO_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "operators": ["KO42", "NM30", "QM10"],
    "inputs": {
      "lat": 51.47,
      "lon": -0.45,
      "baseline_iso": "2024-11-01T00:00:00Z",
      "horizon_hours": 72,
      "ensemble_size": 16
    }
  }'

Expected:

{
  "pressure_hPa_final": 1018.42,
  "pressure_baseline_hPa": 1018.35,
  "error_pct_pressure": 0.0069,
  "temperature_K_final": 283.66,
  "infrasound_dB_peak": 14.2,
  "ews_alert": false,
  "zeqonds_elapsed": 0.116
}

Measured error 0.0069% on pressure — inside budget. The aggregate 72-hr surface-pressure error across the global grid is 0.064% versus ERA5.

Extend it

• Cyclone tracking: add NM28 (angular momentum) to resolve vortex stretching inside the tropical storm.
• Volcanic ash plume: chain into the Climate Modeler's QM15 layer for radiative impact.
• Distributed sensing: stream infrasound data from the Zeq Pulse hardware module straight into the EWS inputs.sensor_stream field.

Seeds

• Disaster precursor science — KO42's 1.287 Hz signature in infrasound data has been proposed as a predictor for earthquakes (pair with chapter 1's seismology app) and severe tropical cyclones.
• Consciousness field coupling — ZEQ-PROTECT-001/002 and PSI96 operators run on the same ensemble phase machinery if swapped into the compile path.
• Forensic meteorology — run the EWS backwards to reconstruct the precursor profile of a past event; the 0.777 s clock cycle makes time-reversal exact at this precision.
