Barometric pressure projected through Z6. The projection friction hides small trends — the compensator reveals them. Storm alerts from friction-calibrated pressure drops. Data from NOAA/NWS + your phone barometer when available.
Six pressure readings at 1-minute intervals form the Z6 input vector. Each reading is quantized to [-3,-2,-1,1,2,3] (no 0 state) relative to the mean: -3 = rapidly falling, +3 = rapidly rising.
terminalColor (6→1, ×6): Collapses 6 readings into 1 output. Only 1/6 of the pressure signal survives — the average trend. The ×6 compensator recovers the full trend amplitude. This is the smoothest weather signal.
couplingBoundary (6→3, ×2): Preserves 3/6 of the signal. The ×2 compensator partially recovers the trend. This shows medium-term weather patterns.
boundMatter (6→6, ×1): Preserves all 6/6. No compensation needed. This shows the raw pressure, including noise and short-term fluctuations.
Storm alert logic: When the TC compensated trend drops by > 0.2 kPa (×6 of the friction-hidden drop), a storm is approaching. The alert is proportional to the friction — a drop that was invisible in the BM regime but appears in TC means the friction was hiding a significant trend.
