Temperature in Calm and Windy Air

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.
