Wind chill

Wind chill, index that determines the relative temperature, based on the effects of wind on exposed human flesh. An increase in wind speed increases the rate at which a person becomes chilled. Thus, the temperature will seem to be colder when there is wind than when there is not. Wind chill measurements are not exact, but they do reflect more how a person feels the cold than a thermometer reading of temperature alone.
