Atmospheric stability and lapse rate

Icebound's post is well-written and almost exactly accurate. Just one
quibble:

The dry adiabatic lapse rate is not an experimentally determined
number.

I simply meant that it is a number which, one way or another, is
more-or-less known. It was a bit of a typo... "experimentally" should not
have been there, but I didn't want to say "theoretically", because I worried
pilots might think that the number is some kind of guess and not really
known.

Saying "Experimentally" didn't alter the gist of the post for pilots... only
for research-meteorologists! :-)
