WIND CHILL

Wind chill is a measure of the effect of wind on our perception of temperature.

Through a process known as convection, 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 Monitor II 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 Monitor II also records the lowest wind chill reading at your loca-

tion.
