If this doesn't work, then check it out at Uses a standard factor for skin tissue and assumes a no sunlight scenario Is based on the latest heat transfer theory, i.e., heat loss from the body to its surroundings, during cold and breezy/windy days Uses calculated wind speed at an average height of five feet (typical height of a human face) based on readings from the national standard height of 33 feet (typical height of an anemometer) The index will be implemented in Canada and the United States in order to have a consistent WCT Index for North America. In this way, an accurate and consistent measure will be provided to help the public protect itself against the dangers of frostbite and hypothermia. Led by the NWS, implementation of the standardized WCT Index will take place throughout the nation and will involve the entire meteorological community and the media - which will play an important role in explaining the index to the general public. In addition, clinical trials have been conducted and the results of those trials have been used to verify and improve the accuracy of the new formula. The new Wind Chill/Temperature Index will make use of advances in meteorology, biometeorology and computer modeling to provide a more accurate, useful formula for calculating the dangers from winter winds and freezing temperatures. Chaired by the NWS, the group's goal was to internationally upgrade and standardize the Wind Chill Index. During the Fall of 2000, a special group - consisting of the National Weather Service, MSC and the International Society of Biometeorology - evaluated the existing wind chill formula and made changes to improve upon it. The reason for the change is to improve upon the current index used by the NWS and the Meteorological Services of Canada (MSC) which is based on the 1945 Siple and Passel Index.įor over a year, there has been discussion within the NWS and MSC about updating the WCT. The National Weather Service (NWS) will implement a new Wind Chill Temperature (WCT) index for the 2001/2002 winter season.
