Windchill

When the air is cold and the wind is blowing, heat is removed from the surface of our bodies more efficiently than if the air was still. As a result, the air feels colder than the thermometer suggests. There are different mathematical equations used to quantify the windchill effect, using air temperature, windspeed and humidity. However, the effect will also vary depending on the amount fo insulation provided by body fat and/or clothing.
