NOAA/NWS 2001: Twc=35.74+0.6215T−35.75V^0.16+0.4275T·V^0.16 for T≤50°F and V≥3 mph
How to use this estimate
NOAA/NWS 2001: Twc=35.74+0.6215T−35.75V^0.16+0.4275T·V^0.16 for T≤50°F and V≥3 mph. Exact algorithm evidence: NWS Wind Chill Temperature Index equation (Twc). States the NWS wind-chill equation Twc=35.74+0.6215T−35.75V^0.16+0.4275T·V^0.16 for °F and mph. Out of scope as listed — not a stamped design.
