Generalized Available Potential Energy

The kinetic energy generation in either the dry or moist atmosphere may be estimated by the same relationships if we introduce the new concept of generalized available potential energy. The largest magnitude of generalized availa-ble potential energy and corresponding reference state of either dry or moist atmosphere are calculated in terms of the initial conditions and entropy variation of the atmosphere. The obtained relationships are applicable for the statically unstable atmosphere as well. The generalized available potential energy associated with reversible processes reaches the maximum with respect to same initial state. While the generation of kinetic energy in irreversible processes is characterized by sudden changes. When the reference state is assumed to be saturated, we may predict the final tem-perature and moisture fields corresponding to provided initial state and entropy variation.
