Back in the day, they used to give us "dry bulb", and "wet bulb" temperatures.
Dry bulb is exactly that, a dry bulb, same as the sump in your vehicle.
Wet bulb had the bulb surrounded in a damp sponge, with the sponge evaporating water off, and running cooler than the dry bulb. (look at old desert and Aussie films, and there was a canvas water bag swinging on the front of the vehicle to provide cool water, relying on this effect.
The difference between the dry and wet bulbs tells you something about the humidity of the air (the closer they are together, the more humid it is, and the less evaporation can take place)...e.g. 100F "dry heat", and 100F coastal humid feel massively different, because your sweat can evaporate in the dry heat, and can't in the humid...exactly why your swamp cooler works in the desert and doesn't at the coast.
Wind chill is the additional temperature drop that a moist body (like us) can experience in dry, mobile air...and we love it in hot weather.
As a big example, some power stations are dry cooled (like car radiator, only footbll fields worth), and others have the traditional cooling towers...there will be a 20-30F difference in operating temperatures between the two...the tower being more efficient (cooler), but evaporating 5-6MG/day to do it.
