Wind Chill Factor
Increased wind speeds accelerate heat loss from exposed skin. No specific rules exist for determining when wind chill becomes dangerous.
WIND CHILL FACTOR: The amount of cooling one "feels" due to the combination of wind and temperature. The formula to calculate wind chill is: WC=.0817(3.71 V^.5 + 5.81 - .25 v)(T-91.4)+91.4 where V=wind speed in MPH and T=temperature F.
Wind Chill Factor- The apparent temperature which describes the cooling effect on exposed skin by the combination of temperature and wind, expressed as the loss of body heat. Increased wind speed will accelerate the loss of body heat.
Wind Chill Factor - It's a number that expresses the cooling effect of moving air at different temperatures. Only air temperature and wind speed is used in the calculation of wind chill temperatures.

The wind chill factor on both days fell way below zero - it dropped to 63 below Monday. These temperatures forced the closing of a number of area schools and set new records for energy use.
The wind chill factor is a measure of this cooling effect. The larger the wind chill factor, the faster the rate of cooling. Note, however, that an object will not be cooled below the actual air temperature, it will just get there faster.
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).
The 'Feels Like' Index displayed in the Observations pages on Weatherzone is a combination of the heat index and wind chill factor.

An extreme case of this effect gives rise to the wind chill factor, where the weather feels colder under windy conditions than calm conditions even though the temperature is the same.
EVAD also estimates the large scale horizontal divergence and particle fall speed. See VWP.
