So, the group of droplets has a greater capacitance to ground than your
single large drop.

It is the full knowledge about atmospheric electricity.

The original total capacitance of the separated drops depends on their
positions- with respect to each other and with respect to ground or
whatever is being used as a reference- this is something that you have
entirely ignored.

They are details.

You are trying to compare a single large drop with 10 electrons to
a single small drop of 1 electron. and haven't even got the math right.
Meaningless!
I was in a hurry. The 100V is for 1000 drops. But I do not know if the
capacitance of drop is proportional to the surface or to the radius. In
painting is assumed that to surface. But it is also detail.

. What becomes important in breakdown (, is not the total voltage to
ground but the high fields in the vicinity of this large charge.

Field are math.

You say it is not possible but it has been found by measurements that
there are regions of positive charge not just different amounts of
negative charges. There is theory backed by experiment that gives at least
one mechanism for this. In addition, there is solid data that some
lightning strokes originate in regions of positive charge. I'll stick
with what is known rather than what you say is not possible.

Could you explain the term "regions of positive charge". There are the two
possibilities:
1. On the drops (or ice) is deficit of electrons,
2. The voltage is lower than in adjacent region

The references that I have given are physics and engineering references-
not meteorologists ' terminology. Consider a droplet that is being swept
up and cooled - there is a difference in mobility between the H+ ions and
the OH- ions in the drop. Suffice it to say that a supercooled droplet may
suddenly freeze (same as water in a supercooled stream can suddenly freeze
from the bottom) and the outer and lighter shards are + and are swept
upward faster and further than the heavier -ve core. Whether this is the
actual mechanism or some other mechanism occurs - there do exist regions
of positive charge (not less negative charge) - as you would know if you
sat down and read some of the technical literature with regard to
lightning. A review of electrostatics might also help. In other words
take time to learn more about the subject before making patently incorrect
statements.

I have had resently a glance at:
http://www.springerlink.com/content/w54350750g275214/
It is obvious that many terms my be incorect understand by readers.
The most important are:
1. Electrification
2. Negative/positive charging
3. Charge separation
4. Charge generation.

Almost all references are in full agreement with my point of view. It is
time to prepare definitions for the above terms ( "A review of
electrostatics might also help")
Could you start with your proposals?
