Wind chill temperature is a measure of the combined cooling effect of wind and temperature. As wind increases, heat is carried away from the body at a faster rate, driving down both the skin temperature (which can cause frostbite) and eventually the internal body temperature (which can kill). The Wind Chill Temperature index is the measure of this relationship.
