Reply to comment by bikerlegs in Why does hot air cool? by AspGuy25

But I’m confused about one thing: wind chill does not reduce actual temperatures. If water is in a chamber at one degree above freezing with a wind chill of 20 below, that water will not freeze. Because the temperature is still above freezing. The only freezing you’d get is due to evaporative cooling, ie an actual drop in the real local temperature of the water.

Metal is not subject to evaporative cooling. So I’m confused as to how wind chill might lower temperatures in a hot chamber. You’d think the wind would bring everything rapidly to the air temperature.

That's correct. Windchill annoys me. It's often misused and confusing. There are Reddit posts saying things like "Here I am in Michigan in a T shirt, it's -60F today". but it's actually 0F with windchill of -60F. And yes, wind does not cool things below ambient unless they are wet (or unless the wind itself is bringing in colder air)
