FAQ: What does wind chill mean?
The wind chill is based on the rate of heat loss from exposed skin caused by the combined effects of wind and cold. As the wind increases, heat is carried away from the body at an accelerated rate, driving down the body temperature.
This temperature is the reading the body "feels" given the combination of wind and air temperature. At wind speeds of 4 mph or less, the wind chill temperature is the same as the air temperature.
