lowering of body temperature due to the passing-flow of lower-temperature air
Wind chill is the decrease in air temperature felt when wind touches the body.
Wind chill numbers are always lower than the actual outside temperature. When the temperature felt outside is higher than the real temperature, the heat index is used.
