The rate at which atmospheric temperature decreases with increasing altitude in conditions of thermal equilibrium.
- ‘For unsaturated moist air the adiabatic lapse rate is almost the same as the dry adiabatic lapse rate.’
- ‘Parcels of air, or thermals, which are isolated from the surrounding atmosphere, cool at a predetermined rate known as the adiabatic lapse rate.’
- ‘All that technobabble is Greek to the Professor, however, whose lack of expertise is such that there is no telling the difference between an adiabatic lapse rate and a diabetic Lap's rat.’
- ‘A representative estimate of the saturation adiabatic lapse rate is 6 Celsius degrees per kilometer.’
- ‘If the lapse rate is less than the moist adiabatic lapse rate, the atmosphere is absolutely stable.’
