Wind Chill Factor

Most of the time, cold is judged in terms of a thermometer reading. With people and other living things though, both temperature and wind speed are needed to produce a “wind chill factor.” The wind chill is based on the rate of heat loss from exposed skin caused by the combined effects of the wind and cold. As the wind increases, heat is carried away from the body at an accelerated rate, driving down the body temperature. The wind chill shows how cold the wind makes exposed flesh feel and is a good way to determine the potential for frostbite or hypothermia.

Remember, wind chill temperatures apply only to people and other living things. If the temperature is 35 degrees F and the wind chill is 10 degrees F, objects such as pipes or cars will only cool to 35 degrees F. The wind chill factor does not apply to non-living objects.
