"During thunderstorms a charge separation takes place in a cloud by a
process which is the subject of several theories but is still not fully
understood....Usually positive charges drift to the upper layer of a
cloud and the bulk of the cloud becomes negatively charged"

What means "positive charges"?

Also a very abbreviated non-technical summary of lightning indicated in
the following http://thunder.msfc.nasa.gov/primer/primer2.html.

Look than in page 3: http://thunder.msfc.nasa.gov/primer/primer3.html

There is the sketch in "The global electric circuit"
You can see that at fair weather electrons migrate up (small arrows
represets currents - electrons move in opposite direction). They are
atached to H2O. The voltage is low because the aggregates of H2O molecules
are small.
After condensation the voltage arises and the slectrons are send to places
where the voltage is lower.
--------
There is nothing in this simple diagram or the text that gives the
conclusions about the voltages, condensation etc.

The sentence: "Present measurements indicate that an average of almost 1
ampere of current flows into the stratosphere during the active phase of a
typical thunderstorm" cannot be true. Storm cloud send electrons in all
directions.e Global Electric Circuit.

Again, the facts are there and if your conceptions ignore the facts, then it
is quite possible that you are wrong.

the "positive" top of cloud to ground strokes

Positive strokes are inter-clouds where the Earth is the intermediary.
----------
Horsefeathers!
However you are now admitting that positive strokes exist.
------------

I am not interesting in details. "The global electric circuit" is enough
for me.
----------
You claim a flaw in the global circuit model but then it is good enough for
you. In other words, you are happier being ignorant. Why?
