Absolute Instability
consider the
diagram to the right, notice that at 2 km (or
anywhere for that matter):
T_{sp} > T_{up}
> T_{e}
Hence, an
unsaturated or saturated parcel will always be warmer
than the environment and will continue to ascend
This is an example
of absolute
instability
The condition for
absolute instability is:
 G_{e} is the environmental lapse
rate (30°C km^{1})
 G_{d} is the dry adiabatic lapse
rate (10°C km^{1})
 G_{m} is the moist adiabatic
lapse rate (6°C km^{1})
