The Wind Chill Factor was developed in 1941 by Paul Siple and Charley Passel, based on the occurence of heat loss of the human body at various temperatures and wind speeds.
Here,  t is the temperature in degrees Fahrenheit, s is the wind speed in miles per hour.

WindChill[t_,s_]=91.4+(t-91.4)(.478+.301Sqrt[s]-.02s)
