Try thinking of these things as pulses not clouds. They travel the
earth like peristaltic motion in the digestive tract of the planet.
The actual cloud is just something that appears on the line of the
fronts. Whatever is in the air at the time is what is condensed out of
it if the conditions are right.
Condensation has to overcome the regain of heat lost in an incline
when the air rises. (Cyclonic weather draws air upward; anticyclonic
downward.) As it rises it cools and loses vapour to ice or water. As
the water falls it may reheat and be absorbed back into the cloud. If
the drops fall in a cool patch they will not evapourate, nor will they
if they fall fast enough due to droplet size or a downdraught.
That's how I understand it anyway. My forecasting methods seem to fit
that aspect at least. But to say my methods are off the wall is to
understate the case.
