Wind chill is a measure of the effect of wind on our perception of temperature.
Through a process known as advection, wind cools off your body by transfer-
ring heat more quickly into the surrounding air. As a result, when the wind is
blowing, you perceive the temperature to be cooler than it actually is.
The Weather Wizard III automatically calculates wind chill using the wind
speed and the outside temperature readings. Wind chill is expressed as a tem-
perature reading, which can be displayed in either ˚F or ˚C in increments of 1˚.
The Weather Wizard III also records the lowest wind chill reading at your loca-
tion.
