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.
heat index changes at a constant temperature with increasing air moisture. Extensive details are given in the original paper that developed the heat index (Steadman 1979a) to...
The extended heat index can be mapped onto physiological responses of an idealized human, such as heat exhaustion, heat stroke, and even heat death, providing an indication of regional health outcomes for different degrees of global warming. SIGNIFICANCE STATEMENT: The existing heat index is well-de ! ned for most combinations of high temperature
1 Οκτ 2022 · 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 undefined heat index.

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).
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 ...
