Wind Chill |
The importance of the wind chill index is
as an indicator of how to dress properly for winter weather. Wind chill
does not affect your car's antifreeze protection, freezing of water pipes,
etc. In dressing for cold weather an important factor to remember is that
entrapped insulating air warmed by body heat is the best protection against
the cold. Consequently, wear loose-fitting, lightweight, warm clothing
in several layers. Outer garments should be tightly-woven, water-repellant
and hooded. Mittens snug at the wrist are better protection than fingered
gloves.
Wind speeds greater than 40 mph have little additional effect on chilling. In using the table below, values of wind chill below -10° F are considered bitterly cold. Values of wind chill below -20° F are extremely cold -- human flesh will begin to freeze within one minute!
