There have been too many emails on this subject, so this one more shouldn't
hurt. The air temperature is the same. The sensation of a different
temperature has to do with air speed. Higher air speed resulting from fast
blowing results in greater evaporative cooling, and less so as the air speed
decreases. Blowing on the hand at a distance makes it feel that there is a
difference in temperature.

Prove it to yourself with a couple of experiments.
Experiment 1. Make a tube with one or two hands and press it tightly against
the mouth (like a mouthpiece). Do the blowing experiment.
Experiment 2. Use the cardboard from a toilet paper roll and stick a digital
(baby) thermometer into the middle. The thermometer should read in 10ths of
a degree-F. Press it tightly against the mouth and do the blowing
experiment. You will find the temperatures to be the same.

It seems to me that it really doesn't matter what the temperature is. The
important thing is to generate the proper sound or feeling for a given
passage. If it works to visualize different temperatures, then that is a
good thing.

Despite your attempt to prove your superior knowledge (so pleasant to
have you jump down my throat!) and your tone and words suggesting YOU
have the ULTIMATE ANSWER, I stand by my words and the general concept.
I, too, have my sources, highly accomplished and respected.

That is all I will say on the subject.
