Wind Chill

Wind chill is a guide to winter danger

The wind chill is the "perceived" temperature to the human body, based on both air temperature and wind velocity. On a cold, windy day, you body loses more heat than it does on a cold, still day. Heat is literally blown away from your body, causing you to fell colder.

As temperatures fall and the wind howls, we begin hearing about the danger of "wind chill." The wind chill index combines the temperature and wind speed to tell you how cold the wind makes it "feel."

Even though the chill is given as a temperature, it's not really a different kind of temperature.

Low wind-chill numbers shouldn't keep you from going out, they should encourage you to dress properly, however.
