Dear Jonathan
This appears to be a very ad-hoc quantity, and I agree it would not make sense
to try to devise a general physical name for it. Adding atmosphere_stability,
as with the total totals index, provides useful information on what sort of
quantity is it, taking a step towards making it self-explanatory.
Thanks
Jonathan
