        NWS Wind Chill Temperature Index

Cold enough for you? Ever wonder how meteorologists calculate the wind
chill factor?

The List presents a valuable site from the U.S. National Weather Service
which has implemented an improvement over the modified 1945 wind chill
temperature index . Gentle Members shivering in northern climes may welcome
this nuts and bolts site which provides the facts on the wind chill factor.

" . . . NWS implemented a replacement Wind Chill Temperature (WCT) index. .
. The current formula uses advances in science, technology, and computer
modeling to provide a more accurate, understandable, and useful formula for
calculating the dangers from winter winds and freezing temperatures. . .
Standardization of the WCT Index among the meteorological community
provides an accurate and consistent measure to ensure public safety. The
new wind chill formula is now being used in Canada and the United States."

This excellent site includes a downloadable (in PDF format) wind chill
chart, a nifty onsite calculator for determining the wind chill factor in
Fahrenheit and the most relevant data for the recently developed wind chill
index.

information and an ongoing handy reference at:
