There absolutely is. A friend in Arizona has this problem, that cycling down a hill makes you hotter, not cooler.
And of course that's why your oven has a fan.

> windroast
I've been roasted by the Loo winds [0] quite regularly. Not a pleasant experience.
Also see: Heat Index [1].

My experience in Nevada and Arizona has been that when it's 40/43 or more, the wind doesn't make it any worse in terms of how hot it feels. At least in regards to normal activity. Wind is a bit annoying - disappointing - when it's that hot, you expect the wind to feel cooling and it's not.

Up to some absurd temperature (i.e this probably isn't true if you're standing in a bunch of exhaust from a jet engine or a metal casting operation) increased airflow will make sweating more efficient enabling you to shed heat faster than the difference between static and moving air heats you up. Even before air conditioning fans were (and still are) popular in the tropics for this reason.
Feel free to go up in your attic or some other 100+deg (freedom degrees, obviously with a box fan if you don't believe me. I assure you it will be more pleasant with the box fan.

At 36 degrees Celsius of wet-bulb temperature, your body is not able to cool itself.

The maximal temperature when you can still cool down depends on humidity and is exactly 36 degrees Celsius with 100% humidity.

Today when biking downhill the warm wind against my eyes was much more annoying / irritating than 'cool wind'. Can't say if it also made me feel warmer, but definitely annoyed my eyes more.
I am wondering if there is 'windchill' is there also 'windroast'? After all if the body cools down by air streaming along it evaporating the sweat then the evaporation process will speed up but the dry skin will then be exposed to air that is hotter than the skin itself.
So if 10 below + windchill can make it feel like -20 below is it possible for 40 + windroast to make it feel like 50?
