# On the concept of exergy and available enthalpy: Application to atmospheric energetics

@article{Marquet1991OnTC, title={On the concept of exergy and available enthalpy: Application to atmospheric energetics}, author={Pascal Marquet}, journal={Quarterly Journal of the Royal Meteorological Society}, year={1991}, volume={117}, pages={449-475} }

The available enthalpy is an early form of the modern thermodynamic concept of exergy, which is the generic name for the amount of work obtainable when some matter is brought to a state of equilibrium with its surroundings by means of reversible processes.
It is shown in this paper that a study of the hydrodynamic properties of available enthalpy leads to a generalization of the global meteorological available energies previously introduced by Lorenz, Dutton and Pearce. A local energy cycle…
