![]() ![]() The new Wind Chill Temperature Index, by Randall Osczevski of DCIEM and Maurice Bluestein of Purdue University in Indiana, makes use of advances in science, technology and computer modelling to provide a more accurate, understandable and useful formula for estimating the dangers arising from winter winds and freezing temperatures. The group's goal was to internationally upgrade and standardize the Wind Chill Temperature Index. ![]() During the Fall of 2000, a special group – consisting of the National Weather Service, the Meteorological Services of Canada and the International Society of Biometeorology – evaluated the existing wind chill formula and made changes to improve it. They did this by measuring heat loss from water as it froze in a plastic container suspended from a tall pole.įor over a year, there have been discussions between the National Weather Service and the Meteorological Services of Canada about updating the Wind Chill Temperature Index. History: The earliest wind chill index was based on the research of Antarctic explorers Siple and Passel who first measured the combined impacts of varying wind speed and freezing temperatures in 1945. Wind Chill FAQsĮxperimental Temperature/Wind Chill Probability Outlook from the NWS Climate Prediction Center Note also that water will not freeze unless its temperature (not the wind chill temperature) reaches the freezing point. Note that the Wind Chill is only defined for temperatures in the range -45 oF to +45 oF and wind speeds 3 to 60 mph. ( More)Įnter desired values for temperature and wind speed in the appropriate boxes, then press Compute. The reason for the change is to improve upon the previous index which was based on the 1945 Siple and Passel Index. ![]() The National Weather Service and the Meteorological Services of Canada has implemented the new Wind Chill Temperature index for the 2001/2002 winter season. This page can be used to compute the new Wind Chill Temperature index. The Wind Chill Temperature index is the measure of this relationship. As wind increases, heat is carried away from the body at a faster rate, driving down both the skin temperature (which can cause frostbite) and eventually the internal body temperature (which can kill). NOTE:The wind chill calculator only works for temperatures at or below 50 ° F and wind speeds above 3 mph.Wind chill temperature is a measure of the combined cooling effect of wind and temperature. What the temperature feels like to your body: This handy Wind Chill Calculator can be used to determine that effect, which can help riders decide on what type of clothing and accessories to wear for a particular ride.Įnter a temperature and bicycle speed that you would like calculated: Newer cyclists may tend to underestimate the effect of "wind chill" that results from cycling speeds.
