  The Wind Chill temperature you have undoubtedly heard of is simply a measure of how cold the wind makes real air temperature feel to the human body.  Since wind can dramatically accelerate heat loss from the body, a blustery 30° day would feel just as cold as a calm day with 0° temperatures.  The index was created in 1870, and on November 1, 2001, the National Weather Service released a more scientifically accurate equation, which we use today.  Here is a chart for calculating wind chill.  (Please note that it is not applicable in calm winds or when the temperature is over 50°.)

[WIND CHILL CHART]

Average Wind Chill at Mount Washington (°F)

Wind chill (°F) = 35.74 + (0.6215 * T) - (35.75 * (W ^ 0.16)) + (0.4275 * T * (W ^ 0.16))
 
T = Temperature (°F)     W = Wind speed (MPH)
