Abstract
A new formula for expressing the combined effect of wind and low temperature on the steady state cooling of exposed skin was introduced in North America in November of 2001. It replaces wind chill formations that were based on the results of an impromptu experiment that Paul Siple and Charles Passel carried out in 1940 in Antarctica. Although it proved to be useful, many experts have criticized the Siple-Passel formula over the decades since its introduction.The new formula is largely based on an established engineering correlation of wind speed and convective heat transfer. The computer model used to create the new charts and the meteorological and physiological assumptions on which it is based are described. Wind chill is an evolving concept. In the future, it might include solar radiation effects and short-term effects, and the effects of environmental moisture such as fog or spray.
