When this value is low, there is a greater heat transfer from the body to the air.
This phenomenon was documented by Paul Siple and Charles Passel during World War II. Since this value takes air circulation into account, convection caused by body heat has required modification of the original formula. When this value is low, there is a greater heat transfer from the body to the air. Re- ported as a number, it is generally less than the actual temperature because it does not account for humid- ity. This effect was originally calculated in terms of the time necessary for a container of water to freeze if left outdoors, and its formula takes into account wind speed and current temperature. Identify this meas- ure of what the temperature actually feels like on exposed skin.
