Cumulus (Developing)
Stage
qThis begins
with unstable air rises often as some surfaces undergo more rapid heating than others.
qOnly updrafts
are present as air rises and adiabatically cools.
qAt first, the
cumulus clouds grow upward
only for a short distance, then they dissipate (because of re-evaporation)
qEventually,
enough water vapor will be present to sustain vertical cloud development which occurs between 5-20 m/sec (10-45 mph)
q When precipitation begins to fall, the storm
enters its next stage.
