"Wind Chill" is the temperature that it feels like outside to people and animals. It is not actually a temperature scale but a measurement of heat loss from the combined effect of wind and low temperatures. Another way to look at the wind chill factor is that it is the temperature a person feels because of the wind. If you've ever used a fan to cool yourself on a hot day, then you've felt the effects of a wind chill. A breeze doesn't make the temperature drop, but it can make it seem as if the temperature is cooler than it actually is.
