Conditional Instability
consider the
diagram to the right, notice that at 2 km (or
anywhere for that matter):
T_{up}
< T_{e} < T_{sp}
The unsaturated
parcel will be cooler than then environment and
will sink back to the ground
The saturated
parcel will be warmer than the environment and
will continue to ascend
This is an example
of conditional
instability
What is the
condition????
ANSWER
The condition for
conditional instability is:
 G_{d} is the dry adiabatic lapse
rate (10°C km^{1})
 G_{e} is the environmental lapse
rate (7.8°C km^{1})
 G_{m} is the moist adiabatic
lapse rate (6°C km^{1})
