OK, a challenge. to the weatherwatch one, hang a steak out in the wind and see if it only cools to the ambient temp.
To Wiki, well it is a cool source of information, but even I can edit it!
And NOAA's example, "If the temperature is 0 degrees Fahrenheit and the wind is blowing at 15 mph, the wind chill is -19 degrees Fahrenheit. At this wind chill temperature, exposed skin can freeze in 30 minutes" , at 0* flesh can freeze in 30 minutes without wind! and "The only effect wind chill has on inanimate objects, such as car radiators and water pipes, is to shorten the amount of time for the object to cool. The inanimate object will not cool below the actual air temperature. For example, if the temperature outside is -5 degrees Fahrenheit and the wind chill temperature is -31 degrees Fahrenheit, then your car's radiator will not drop lower than -5 degrees Fahrenheit." If your skin is exposed to this, it may feel like -31, but trust me, when you reach -5, you will become inanimate, too, and you will not become any colder
If for some reason you don't believe this, read #9 "
9. Is it possible to get frostbite if the temperature is above freezing but the wind chill is below freezing?
The air temperature has to be BELOW freezing in order for frostbite to develop on exposed skin. Wind chill can bring the temperature to below freezing for humans and animals. " Even while you're still alive, it is ambient temperature that is the limiting factor. You cannot cool below what it really is!
and just because it "feels" like its 15*, doesn't make it 15* and without the effect of that moving air, your radiator will not cool, will it? Oh, give it a try sometime, PLEASE!!
or, maybe you can explain to my dumb arse just how that moving air does remove the heat.
The way wind chill is determined is with wet bulb temperature, kinda like dew point and heat index. It is a perceived event, only.
Sorry Kenny, I, too think it probably was your parking brake, but you try to interject a little humor, and somebody ALWAYS has to call you it
