Adiabatic lapse rate

Latent heat. That is why they spray water on the oranges to
reduce frost damage.

After a day or two at below freezing, but near freezing
temperatures in stable air, there will be little airframe
ice because the water has finally frozen.
But with unstable air, more fresh and liquid water is being
cooled into the supercooled range and that makes structural
ice.

Why dies everyone think that the standard lapse rate is a
meteorological term?

It's not.

Now, our Cherokee 6 can't climb up to FL 350, so I have no personal
experience with how high the standard lapse rate holds. However, my son
will tell you that for a clear day, above 2000' AGL, it seems to hold
very very well.

He got lucky. I can't remember a flight here (UK) where the lapse rate
was anything like 2C/1000ft.

Yesterday, +10C on the ground, +8C at 5000ft.

That might have been because there was an inversion from the ground up to
say 2000 ft, a higher temperature that ground level.

You think it is a cooking term?
Maybe medical, as in "I let my medical lapse".

It is used to model the standard atmosphere, certainly is a
scientific term used in physics, which applies to
meteorological study. It has an application to actual
flight by using terms such as ISA+20

Environmental lapse rate is a meteorological term.

Adiabatic lapse rates are meteorologocal terms.

Standard lapse rates are an invention of engineers to enable them to
compare aircraft performance.
