About The Wind Chill Factor

The reason people and warm blooded animals feel a windchill is that we generate heat internally as we metabolize food and fat. When the wind is blowing and the temperatures are cold enough (as opposed to a hot summer day) our bodies lose this internally generated heat as the air flowing around us carries the heat away. The stronger the wind, the faster this heat loss occurs and the more we "feel" the cold.

The general basis for the wind chill is that the higher the wind speed and the lower the temperature the colder you will feel because the wind is wicking away the heat from the surface of your skin. The wind chill factor comes into effect when the temperature is equal to or less than 4 degrees Celsius and the wind is greater than 8 km/hr.
