#<div class="definition"><div class="short_definition">A [[process lapse rate]] of [[temperature]], the rate of decrease of temperature  with height of a [[parcel]] of [[dry air]] lifted by a reversible [[adiabatic process]] through an [[atmosphere]]  in [[hydrostatic equilibrium]].</div><br/> <div class="paragraph">This [[lapse rate]] is ''g''/''c''<sub>''pd''</sub>, where ''g'' is gravitational [[acceleration]] and ''c''<sub>''pd''</sub> is the [[specific heat]] of  dry air at constant [[pressure]], approximately 9.8&#x000b0;C km<sup>-1</sup>. Potential temperature is constant with  height in an [[atmospheric layer]] with this lapse rate.</div><br/> </div>
