As I wrote at 2/20 6:07 am above the 1996 paper has been followed up, verified and published more recently
by several other independent atmospheric thermodynamic
physicist authors proving Fig. 1 in the top post thought
experiment to be non-isothermal, isentropic at equilibrium (they do include for Willis» sake equations with = signs).
There is however vigorous random mixing of the molecules up and down the ideal gas column at equilibrium in a gravity field leading to non-zero pressure and non-zero temperature gradients at equilibrium proven
by reasonable
experiment and theory of published
physicists.
The thought
experiment of Fig. 1 in top post being isothermal at equilibrium is wrong & shown irrefutably (
by many published atmospheric thermodynamic
physicists cited) to be non-isothermal, isentropic in equilibrium
by the correct algebraic steps to maximize entropy and reasonable
experiments as posted above.
There is no convincing evidence found of an atmospheric
physicist publishing a proof otherwise
by experiment or theory since then.
entropy, conserving total enthalpy / energy equilibrium of Fig. 1 is irrefutably proven non-isothermal, isentropic
by published atmospheric thermodynamic
physicists as early as 1996, again in 1998, 2004 and 2010 including
experiments validating their results.
Independent atmospheric
physicists verified Fig. 1 is non-isothermal, isentropic in equilibrium again in 1998, 2004 and 2010
