Revised Wind Chill Temperature

The formula for calculating the wind chill temperature - the perceived temperature on exposed human flesh for various wind speeds - is being revised to more accurately estimate wind effects based on recent studies. The new description is at -

• http://www.crh.noaa.gov/dtx/New_Wind_Chill.htm

For the record, the formula is -

wind chill(F) = 35.74 + 0.621T - (35.75 * (V**0.16)) + (0.4275 * T * (V**0.16))

where T is in degrees fahrenheit,
V is wind speed in miles per hour
