Question

Quizplus · Accepted Answer

The wind-chill temperature index is a factor of both the actual air temperature and wind speed. It calculates the rate of heat loss from skin exposed to the elements, taking into account the evaporative cooling effect of wind on bare skin. It does not consider infrared solar radiation, assume anything about protective clothing, use the same variables as the heat index, or take into account physical activity.
