Environmental Stewardship: Wind Chill

“Wind chill” has an interesting history. The first attempt to quantify the effect of wind on heat loss was back in 1945 by a couple of explorers in Antarctica, Paul Siple and Charles Passle. They stuck bottles of water out in the wind and timed how long the water took to freeze. They reported the heat loss in watts per square meter, which would really confuse the modern TV viewer.
