![]() It was later adopted by the National Weather Service to help communicate the impact of cold wind on exposed skin. The calculation has been tweaked since being introduced.Īnd if you really, REALLY want to show off, here's the wind chill formula, according to the University of Kentucky: T(wc) = 0.0817(3.71V**0.5 + 5.81 -0.25V)(T - 91.4) + 91.4 (A historical footnote: The wind chill was “invented” by researchers Paul Siple and Charles Passel in Antarctica in 1945. Some people may be more tolerant of the cold than others, but we all feel it. Objectively, because we’re warm-blooded creatures we all feel varying degrees of cold with or without wind thrown into the mix. Wind chill formulaīut, do people all feel temperature in the same way? That gets more into the philosophical realm. Being an inanimate, non-living thing, water is not impacted by wind chill. The water will come to equilibrium with the air and settle at a temperature of 40 degrees, the ACTUAL temperature of the air. Here’s an example: Some people may think that air at 40 degrees but with a wind chill of 25 (thanks to a strong breeze) might freeze water. It determines whether we get snow or rain. Wind chill has no impact on any of these things. Actual temperature determines whether water freezes or stays liquid. ![]() ![]() It applies to everything else besides wind impacts on exposed skin. Regarding the question, “What’s the point of the actual temperature if that’s not what it ‘feels like’?” - the simple answer is that the ACTUAL temperature is EXTREMELY important!
