The Heat Index (or apparent temperature) is the result of extensive biometeorological studies. The parameters involved in its calculation are shown below (from Steadman, 1979).
Table H1 Figures from Steadman (1979a), which give the heat index in the form of an apparent temperature as a function of the actual temperature and dewpoint. Table H2 Figures also from Steadman (1979a), which give the heat index in terms of air temperature and relative humidity.
ABSTRACT: The heat index is a widely used measure of apparent temperature that accounts for the effects of humidity using Steadman’s model of human thermoregulation. Steadman’s model, however, gives unphysical results when the air is too hot and humid or too cold and dry, leading to an unde ned heat index.
1 Οκτ 2013 · Between Steadman’s two original tables (1979a), heat index values calculated using Steadman’s original physiological models are available for air temperature between 20°C/68°F and 50°C/122°F, relative humidity between 0% and 100%, and dew point temperature between 0°C/32°F and 30°C/86°F (Figures 1B, ,2B). 2B). For each of the 21 ...
