![]() ![]() Bluestein, who was trained as a mechanical engineer, had not given much thought to the science behind the weather until he was shoveling out his daughter’s car from under a snowdrift one evening in January 1994 in Indianapolis. His daughter Karen Bluestein said the cause was esophageal cancer.ĭr. 28 in Pompano Beach, Fla., where he lived. One of the two was Maurice Bluestein, who died at 76 on Aug. It’s then calculated as per the equation below. For instance, according to the North American Index, wind chill factors in the wind speed (V) along with ambient temperature (T), as opposed to your riding speed. The National Weather Service had been calculating the wind chill since the 1970s, but not very accurately, until two scientists set out in 2001 to perfect the measure and make it more reliable. The blue-shaded areas in the wind chill chart represent the amount of time it takes to get frostbite on exposed skin at the corresponding wind chill temperatures. Nonetheless, global standards haven’t been set. It considers wind, in addition to temperature, to calculate the loss of heat from the body. The result is the wind chill index, a number that attempts to tell us how cold it might feel rather than simply how cold it is. It’s how it feels when you’re out in cold weather with wind. ![]() As the wind increases, it draws heat from the body, driving down skin temperature and eventually the bodys internal temperature. On frigid winter mornings, when weather forecasters are trying to describe whether it’s a hat-scarf-gloves day or if just a warm coat will do, they will take the temperature (T) and wind speed (V) and plug the numbers into a handy equation: WCT = 35.74 + 0.6215T – 35.75V 0.16 + 0.4275TV 0.16. Wind chill is based on the rate of heat loss from exposed skin caused by the combination of wind and cold, according to the National Weather Service.
