Wind Chill

by Hailee

Wind chill is the cooling temperature our body feels when our temperature and wind combine. Our body temperature makes a sort of protection from the temperature outside. The added insulation is called a boundary line.

If the wind chill range 0 to -9, the rating is low. The impact is minor increasing discomfort. 10 to -24 is moderate and uncomfortable. -25 to -44 is cold and danger of frostbite. -45 to -59 is extreme and exposed skin may freeze. -60 or colder is a dangerous high risk; if possible stay indoors.

The wind chill formula was based on experiments. The experiments were made by two explorers. In the year 2000 Canada decided to develop a new wind chill formula.

Wind chill is based on the rate of heat loss. When wind increases, the body heat decreases.

If it is a cold winter day, wind chill can be everywhere. The wind chill factor is what makes wind chill.

On a cold day, our body can make a thin layer of skin. The skin layer is unseen by the naked eye; It is like clothes.

The greater the wind speed, the faster we lose body heat. A winter day can be colder when there is wind chill.
