when dry or unsaturated air rises, its
rate of fall of temperature with height
(i.e. lapse rate) is constant at 3°C per
1,000 feet. Similarly, descending air
warms by compression at that rate.
This dry adiabatic lapse rate is
normally referred to as the DALR. Air
rising and cooling often reaches its
dew point temperature, becomes
saturated and any further cooling
results in condensation and the
release of latent heat. Release of
latent heat delays the cooling process
and the lapse rate at low levels is
reduced to 1.5°C per 1,000 feet. This
temperature change is called the
saturated adiabatic lapse rate and is
normally referred to as the SALR.
