Wind Chill 風寒指數
--
|
It is the index that combines air temperature and wind speed to estimate how cool one actually feels. (We usually feel colder on a windy day than on a calm day with similar air temperature readings. It is because winds can carry away the heat energy that is trapped next to our skin and induce heat loss through evaporation of any moisture on our skin.) (Reference: Wind Chill Program of Environment Canada's World Wide Web Site) |

Heat Index 酷熱指數
--
|
It is the index that combines air temperature and relative humidity to estimate how hot one actually feels. (If the relative humidity is high, we may feel hotter than the air temperature recorded. It is because the moisture around slows down evaporation. Our body heat cannot be released easily.) (Reference: National Weather Service of NOAA) |
