We're dealing with two misconceptions here. Wind chill is not affected by evaporative cooling. You can of course go below ambient with evaporative cooling, or air conditioning, or any number of methods. Wind chill is explicitly and only the experienced subjective temperature caused by cold air being continuously replaced by the wind. For example, take the US National Weather Service's wind chill formula, which only uses wind speed and tempurature as inputs and provides the wind chill in W/m². Source: https://www.weather.gov/media/epz/wxcalc/windChill.pdf https://www.weather.gov/media/epz/wxcalc/windChill.pdf > Wet bulb temperature is not “the true temperature of the environment”. Besides, that is true for humans as well, so again not any different between living and non-living things. Wind chill and evaporative cooling are independent mechanisms, and the wind chill value and wet bulb temperature are separate values. My reply was to your original comment, which said: > For second the coldest wind chill recorded in the US was -100°F at McGrath, Alaska in 1989. That value is not the temperature that an object could have reach at that time and place. It is the wind chill, an approximation of how cold it would have to have been on a windless day to make a person subjectively feel equally cold.
