Current: Potential temperature is the temperature a parcel of air or sea water would have if moved adiabatically to sea level pressure.Proposed: The phrase "equivalent potential temperature" refers to a thermodynamic quantity, with its natural logarithm proportional to the entropy of moist air, that is conserved in a reversible moist adiabatic process.

The "equivalent potential temperature" is a thermodynamic quantity, with its natural logarithm proportional to the entropy of moist air, that is conserved in a reversible moist adiabatic process. Reference: AMS Glossary http://glossary.ametsoc.org/wiki/Equivalent_potential_temperature. It is the potential temperature of a parcel of air if all the moisture contained in it were first condensed, releasing latent heat, before moving the parcel dry adiabatically to sea level pressure.

The "equivalent potential temperature" is a thermodynamic quantity, with its natural logarithm proportional to the entropy of moist air, that is conserved in a reversible moist adiabatic process. Reference: AMS Glossary http://glossary.ametsoc.org/wiki/Equivalent_potential_temperature. It is the temperature of a parcel of air if all the moisture contained in it were first condensed, releasing latent heat, before moving the parcel dry adiabatically to a standard pressure, typically representative of mean sea level pressure. To specify the standard pressure to which the quantity applies, provide a scalar coordinate variable with standard name reference_pressure.
