Anemometer#

Anemometers measure wind speed using mechanical rotation or pressure differences. Their behavior is stable, predictable, and grounded in well‑characterized physical principles.

Dimensional Core (SET)#

• Spin: rotational sensing (cup or vane types)
• Elec: optional electronic readout
• Temp: minor influence on air density

Why Green‑Zone#

Anemometers operate in a clean, coherent regime.
Their measurement principle is direct, substrate‑agnostic, and minimally dependent on inference. Calibration is straightforward, and environmental sensitivity is well understood.

Regime Notes#

• pos‑regime: steady airflow, linear response
• Q‑regime: gusts, turbulence, density variation
• neg‑regime: extreme storms, mechanical stall, icing

Alignment Notes#

Already aligned.
Only edge‑case conditions (icing, turbulence spikes) require explicit regime boundaries.
