Towards the beginning of the video in the referenced article, I noticed that the gentleman (male voices) holding the digital thermometer spins the probe in circles. Doesn’t spinning the probe possibly introduce false lower temperature readings as a result of artificial wind chill?

It possibly could, but you need moisture in the air to cause evaporative cooling, and at those temps, the air is pretty dry.

Wind doesn’t affect thermometer readings. If it’s 5 degrees with a wind chill of -10, the thermometer will show 5 degrees.

Spinning the probe gets it to the ambient temperature more quickly.

No.

Wind Chill does not lower temperature of an object below the ambient temperature.

Wind Chill is a measurement of how fast leaves a warmer object as compared to without wind. Things like living creatures, heated homes, etc are affected by wind chill as the heat needs to be replenished faster to maintain the same warmer temperature. Once an object is cooled to the ambient temperature, like a rock or a thermometer, has no effect.

Supplying a little extra wind by spinning it around, just gets the thermometer to the actual temperature faster (if you had kept the probe indoors, instead of leaving it outdoors).
