AI2_9 體感溫度

The heat index formula 酷熱指數公式 is expressed as,

HI = c1 + c2T + c3R + c4TR + c5T2 + c6R2 + c7T2R + c8TR2 + c9T2R2

where,

· HI denotes the heat index 酷熱指數 in degrees Fahrenheit °F

· R denotes the relative humidity 相對濕度

· T refers to the temperature 溫度 in °F

c1 = −42.379

c2 = 2.04901523

c3 = 10.14333127

c4 = −0.22475541

c5 = −0.00683783

c6 = −0.05481717

c7 = 0.00122874

c8 = 0.00085282

c9 = −0.00000199

°F = 9/5 × °C + 32

°C = (°F-32)× 5/9
