The climate becomes colder at high elevations this characteristic is described by the dry adiabatic lapse rate is 10 �C per km ( 5.5 �F per 1000 ft ) of elevation or altitude.
22.
The rate of decrease of temperature with elevation is known as the adiabatic lapse rate, which is approximately 9.8 �C per kilometer ( or 5.4 �F per 1000 feet ) of altitude.

If the adiabatic lapse rate is " lower " than the ambient lapse rate, an air mass displaced upward cools " less " rapidly than the air in which it is moving.
25.
Once the CCL is determined, the surface temperature necessary to raise a mass of air to that height can be found by using the Dry Adiabatic Lapse Rate ( DALR ) to determine the potential temperature.
26.
The dry adiabatic lapse rate accounts for the effect of the expansion of dry air as it rises in the atmosphere and wet adiabatic lapse rates includes the effect of the condensation of water vapor on the lapse rate.

28.
The environmental lapse rate ( the actual rate at which temperature drops with height, dT / dz ) is not usually equal to the adiabatic lapse rate ( or correspondingly, dS / dz \ ne 0 ).
29.
Conversely, if the adiabatic lapse rate is " higher " than the ambient lapse rate, an air mass displaced upward cools " more " rapidly than the air in which it is moving.

In the Himalayas, the rate at which an air mass's temperature falls per kilometre ( 3, 281 ft ) of altitude gained ( the dry adiabatic lapse rate ) is 9.8 �C / km.
