Clothing, Wet-cold and Exposure Duration
Wet clothing and the duration of a person's exposure to wind also affect the felt air temperature. The wind chill formulae do not take account of the variation of clothing worn and how wet or dry a person is. The typical assumption is that a person will be properly dressed and dry. Models generally also assume that thermodynamic equilibrium exists, something that might not be the case if a person quickly run outdoors and back indoors, for example.

Famous quotes containing the word duration:
“Higher than the question of our duration is the question of our deserving. Immortality will come to such as are fit for it, and he would be a great soul in future must be a great soul now.”
—Ralph Waldo Emerson (1803–1882)
