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.
