  4. Characteristics of the study 1. The Wind Chill Temp must < air temp 2. Such Measurement is valid only when -- Wind speed > 3 mph -- Air temp < 10 0C -- Air speed in kmh-1 measured at 10m This work by Tong Man Chung from The Chinese Foundation Secondary School is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Hong Kong License To view a copy of this license, visit http://creativecommons.org/licenses/by-nc-sa/3.0/hk/deed.en_HK

  5. Formula for student measurement Twc = 13.12 +0.6215Ta– 11.37V0.16+ 0.3965TaV0.16 where Ta: air temp, V: wind speed Twc: Wind Chill Temp This work by Tong Man Chung from The Chinese Foundation Secondary School is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Hong Kong License To view a copy of this license, visit http://creativecommons.org/licenses/by-nc-sa/3.0/hk/deed.en_HK
