–Rain is associated with warm clouds exclusively and cool clouds when surface temperatures are above freezing
–Rainshowers are episodic precipitation events associated with convective activity and cumulus clouds
•Drops tend to be large
and widely spaced to begin, then smaller drops become more
prolific
–Raindrop Shape
begins as spherical
•As frictional drag increases, changes to a mushroom shape
•Drops eventually flatten
•Drops split when
frictional drag overcomes the surface tension of water
•Splitting ensures a
maximum drop size of about 5 mm and the continuation of the
collision-coalescence process
