Question:
If the air temp is 90 degrees F, will increasing wind change the air temp? I am not talking about body cooling. Just air temperature. Example - temperature = 90 F measured by a thermometer. Turn a fan in the direction of the thermometer, will the temp fall?


Replies:
Monique,

Not unless the thermometer is wet.

Brian,

No, the temperature will not decrease from air movement. Air movement will only decrease the temperature of an object from which evaporation of water would occur, such as a human's skin.

The "short" answer is NO, under "normal" conditions. You pointed out a major condition -- that there is no evaporation of water. Among some others are that the air speed does not result in any frictional heating by the air, that there is no significant decrease/increase in the air density, that the air speed is much less than the speed of sound, etc.
