Comfort vs. dry bulb, wet bulb and dew point temperature.
The Discomfort Index can be expressed as
DI = 0.4 (td + tw) + 15 (1)
DI = 0.55 td + 0.2 tdp + 17.5 (1b)
DI = Discomfort Index
td = dry bulb temperature (oF)
tw = wet bulb temperature (oF)
tdp = dew point temperature (oF)
The higher the value - the higher the value of discomfort.
