What Is Wind Chill?


By By Steve Pool

SEATTLE - Ever notice how on especially cold days, that it can be made to feel even colder when there's a stiff breeze?

The wind chill temperature was developed to give people a general idea of how much colder it feels when the wind is blowing. The stronger the wind, the colder the wind chill.

It feels colder when the wind blows because the wind will blow away the layer of warmth that your body produces near the surface of your skin. (Think of it as pulling away your natural blanket).

Note that the actual temperature does not change -- if it's 40 degrees with a wind chill of 25, water will not freeze. Wind chill only applies to humans and animals and does not affect inanimate objects.

I didn't have a toad on hand but this fungus was too perfect to waste. The Jack O lanterns is from a Halloween light set. The dandelion is from my garden of volunteer flowers.

Each year since 1998 our family has a tradition of putting up a scarecrow in our front yard during the month of October. We decide as a family what character we are going to do and it's a family secret until he goes up. Most of the time we create the entire outfit from scratch.
