In well mixed air which is dry for every 100m MCI c
ase in altitude, the temperature decreases by
about 1o C. This vertical temperature gradient is k
nown as dry adiabatic lapse rate (DALR).
Ambient and adiabatic lapse rates are a measure of
atmospheric stability. Since the stability of
the air reflects the susceptibility of rising air p
arcel to vertical motion, consideration of
atmospheric stability or instability is essential i
n establishing the dispersion rate of pollutants.
The atmospheric is said to be unstable as long as
rising parcel of air remains warmerthan the surrounding air
Conversely, when a rising parcel of air arrives at
an altitude in a colder and denser state
than the surrounding air, the resultant downward bu
oyancy force pushes the parcel of air
downward (Earthward) and away from the direction of
displacement. Under such conditions
atmosphere is said to be stable.
Stability is a function of vertical distribution of
atmospheric temperature and plotting the
ambient lapse rate can give an indication of the st
ability of the atmosphere. Though dry, moist or
wet adiabatic lapse rate may be used, in such a com
parison, the DALR issued as the measure
against which several possible ambient lapse rates
are plotted. Thus the boundary line between
the stability and instability is DALR
When ALR exceeds DALR, the ALR is said to be SUPER
ADIABTIC and the
atmosphere is highly unstable. When the two lapse r
ate are exactly equal, the atmosphere is said
to be neutral. When the ALR is less than the DALR,
the ALR is termed SUB-ADIABATIC and
the atmosphere is stable. If air temperature is con
stant throughout a layer of atmospheric, ALR
=O, the atmospheric layer is described as isotherma
l and the atmosphere is stable.
When temperature of the ambient air increases rath
er than decrease with attitude, the
lapse rate is negative or inverted from the normal
state. Negative lapse rate occurs under
conditions, commonly referred to as an INVERSION, a
state in which warmer air blankets colder air
