eli5: Why does the breeze feel cool?

962 views

If the air is moving faster that means it has higher energy and is hotter, right? If it hits my skin with a higher velocity it is transferring more energy than if it were moving slower. Both of these reasons suggest faster winds should feel hotter but they don’t, the stronger the breeze the cooler it feels. Why?

Measuring things at stasis is surprisingly hard for nerve cells, so we in general sense and feel the DIFFERENCE between conditions.

Lets say your skin is 80F, breeze comes by and it’s only 70F; You feel it as cold since your skin is losing heat to try to heat up the air its in contact with to also be 80F.

Now… lets say it’s hot out, and both the air and your skin are 80F, what about the water in the air? Your skin is hot and sweaty… but the air isn’t as humid as your skin yet! Water is going to evaporate, which takes heat out of your skin, and the warm water vapor goes away leaving your skin colder than it used to be as the breeze goes by. You feel that as a nice cool breeze. 🙂

Now… if you live in hell, and it gets both hot and humid… breezes always suck since you never loose heat or sweat.

In your post, you seem to treat kinetic velocity, and heat as interchangeable which isn’t the case here.
