| The formula for determining the wind chill is expected to be revised in November, thanks to IUPUI Professor Maurice Bluestein and Randall Osczevski, a Canadian physicist. They worked together at the request of the U.S. National Weather Service and the Meteorological Services of Canada. The two agencies suspected that the previous formula has been flawed in producing estimates of wind chills that are too cold.
Bluestein says that the original calculation of wind chill was determined more than 50 years ago, the researchers then using a can of freezing water in the Antarctic. Instead, Bluestein and Osczevski used a model of the human face and 12 volunteers walking on a treadmill in temperatures and wind speeds that varied. | |
