This page can be used to compute the new Wind Chill Temperature
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. The reason
for the change is to improve upon the previous index which was
based on the 1945 Siple and Passel Index. (More) Enter desired
values for temperature and wind speed in the appropriate boxes,
then press Compute. 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. They did this by measuring
heat loss from water as it froze in a plastic container
suspended from a tall pole. For 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. During the Fall of 2000, a special group,
consisting of the National Weather Service, the
