Wind Chill Index
(Wind Chill Factor, Chill Factor) Index used to determine the relative discomfort resulting from a specific combination of wind speed and air temperature, expressed by the loss of body heat in watts per square meter (of skin).

Wind chill index (also called wind-chilled factor.) The cooling effect of any combination of temperature and wind, expressed as the loss of body heat in kilograms per hour per square meter of skin surface.

Wind Chill Advisory- Issued when the wind chill index is expected to be between -25F and -39F for at least 3 hours. This is using the wind chill of the sustained wind, not gusts.
