NWS Wind Chill Temperature Index http://www.nws.noaa.gov/om/windchill/index.shtml Cold enough for you? Ever wonder how meteorologists calculate the wind chill factor? A valuable site from the U.S. National Weather Service which has implemented an improvement over the modified 1945 wind chill temperature index . " . . . 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." - from the website 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. ~*~*~*~*~ Was this forwarded to you?
