<div class="definition"><div class="short_definition">(<br/>''Or'' saturation-adiabatic lapse rate.) The rate of decrease of [[temperature]]  with height along a [[moist adiabat]].</div><br/> <div class="paragraph">It is given approximately by &#x00393;<sub>''m''</sub> in the following:  <div class="display-formula"><blockquote>[[File:ams2001glos-Me16.gif|link=|center|ams2001glos-Me16]]</blockquote></div>  where ''g'' is gravitational [[acceleration]], ''c''<sub>''pd''</sub> is the [[specific heat]] at constant [[pressure]] of [[dry air]], ''r''<sub>''v''</sub>  is the [[mixing ratio]] of [[water vapor]], ''L''<sub>''v''</sub> is the [[latent heat]] of [[vaporization]], ''R'' is the [[gas constant]]  for dry air, &#x003b5; is the ratio of the gas constants for dry air and water vapor, and ''T'' is temperature.  This expression is an approximation to both the reversible moist [[adiabatic lapse rate]] and the  [[pseudoadiabatic lapse rate]], with more accurate expressions given under those definitions. When  most of the condensed water is frozen, this may be replaced by a similar expression but with ''L''<sub>''v''</sub>  replaced by the latent heat of [[sublimation]].</div><br/> </div>
