The heat index (HI) is the "apparent" temperature seen from the combined effects of environmental temperature and humidity.
Parameters:
(1) ambient dry bulb temperature in °F
(2) relative humidity in percent (from 0 to 100)
heat index =
= (a * (temperature)) + (b * (humidity)) + (c * (temperature) * (humidity)) + (d * ((temperature)^2)) + (e * ((humidity)^2)) + (f * ((temperature)^2) * (humidity)) + (g * (temperature) * ((humidity)^2)) + (h * ((temperature)^2) * ((humidity)^2)) - 42.379
