formula for windchill?

Factual Questions
1

Someone ask me the other day how meteorologists figure the windchill…when they say the temp is 35 degrees but it feels like 28 degrees what formula are they using?? Anyone?

I got this off of Dr. Dewpoint on Intellicast. (insert TM symbols where they belong). http://www.intellicast.com/DrDewpoint/Q_A/2029/

Well I meant to add this to the previous post.
The following equation can be used if the wind speed in mph (V) and the temperature
in deg. Fahrenheit (T) are known (SQRT = square root):
TWC=91.4-((91.4-T)(.478+(.301SQRT(V))-.02*V))
(NOTE: AT WIND SPEEDS OF 4 MPH OR LESS, TWC IS THE SAME AS THE ACTUAL AIR TEMPERATURE).

Isn’t the WCF considered to be almost constant at very high wind speeds, including as that speed increases markedly? Does this formula take account of this?

I don’t really know, the only note had to do with the lower end that I saw.
