Still, for anyone pursuing a degree in physics with a specialty
in Meteorolgy, at least from any major university, they will have done
at least two balloon lauches ard interpreted the radiosonde results as
a lab requirement. These are the same students that a year or two
earlier would have been measuring the charge on an electron by
repeating the "Oil Drop" experiment (******* and boring experiment
that it is), every physics student has to perform it.

In the "Oil Drop" experiment charged droplets migrate up in the electric
field. If all students perform this experiment than all meteorologist should
know that the charged water droplets migrate up in the Earth electric field.
And that all water droplets in clouds have the excess of electrons
(negatively charged). Why when in meteorology some parts of clouds are
positively (deficit of electrons) charged?

Just to explain why I might hold such an openly opinionate view of
meterology, enter Dr. Francis Davis into my life.

http://www.angelfire.com/tv2/broadca...ers/davis.html

Dr. Davis was the local Philadelphia weatherman during the years that
I attended Drexel, and he was the professor of meteorolgy when I took
the subject as a physics elective while I was earning my undergraduate
degree. Dr. Davis was a somewhat harsh taskmaster, and his persona on
TV was nearly counter to the demands for performance that he placed on
his Drexel physics students (I believe there were only 21 of us during
those years), in a college of roughly 3,000 students (back around
1963). He was a very strict grader, and not one exam involved multiple
choice questions. All were computations, required to be performed in
ink in the dreaded Drexel "blue books". Most Drexel grads of that era
know exactly what I refer to.

Actually, at the time, I really liked the guy, but then I also liked
Dr. Tartler in the math department, who was generally believed to have
flunked his own son out of Drexel due to poor performance in math. The
profs at Drexel in those days were pretty "hard core" compared to what
exists today!

At the start of my senior year at Drexel (then Drexel Institute of
Technology), Dr. Davis replaced Dr. Wehr (a nuclear scientist) as head
of Drexel's Physics Department. That was the year that I graduated
and acquired my BS in Physics. So, I guess that you could say that my
undergraduate degree in physics was signed and approved by our local
Philadelphia, TV weatherman. Fortunately, that did no sway Princeton
from both accepting me into their graduate school, or hiring me as a
research employee at Forrestal.

Dr. Davis was a very interesting guy, who in my mind had a dual life
(of the best kind). On one hand he was the most popular TV weatherman
in the Philadelphia/NJ/Delaware area, and at that same time was a
respected physicist. Few people can compete with that!

I post this simply to let readers know the foundations that form the
basis of my blunt opinions. Opinions that if they offend anyone, then
that's just too damn bad.

Say Harry, ((Harry)), I reed yor posts to lurn beter
spelin an gramer.
Seriously, IMHO you're a top poster.

Ken, thanks yer very much for you comments.

I post on the fly, without a spelling or grammar checker, but I do
post completly honestly, and you can bet on that.

My wire is the grammare and spelling export, I'm simply a physucist
that was originally intended to be a tennant farmer in NJ. The wire,
she taches s;elling to kids that are, while not riding the short bus,
and in need of help. She has this amazing ability to bring kids that
are 3-years below grade level, up to grade level in about 6-months.
Fer me, this is amzing, and I wsh that she could do it for me.

Sandy is one of those few amazing people that you encounter in a
lifetime, totally devoted to her students, and she obtains incredible
results. Our house is flooded by flowers at the end of each school
year, not sure that I know why, because she hasn't yet even mastered
differential calculus!

What a combination we two are, but regardless we were married on July
11, 1959, and if I can still do simple arithmetic, by July 11, 2009 we
will celebrate our 50th anniversity. The bad thing is that none of our
close friends will be alive to notice that event, except for our 3
children and a couple of our neighbors. Definitely, firworks will be
shot, and I doubt that the police will take notice.

Ogh, thixs is sci.physics, I lust trek thare and thought that for a
mombnet, it was rec.pyrotechnics.

p.s., Beware of the 'Old Farts' that you may encounter from time to
time on the Newsgroups. Many will play dumb, but anthing else may be
true. You never know!

But my question was: "Why then in meteorology some parts of clouds are
positively (deficit of electrons) charged?

We can read everywhe "How rain clouds become charged is not fully
understood, but most rain clouds are negatively charged at the base and
positively charged at the top"

It is impossible. Each part of each cloud is negatively charged. Only the
voltages may be different In meteorology should be tha same laws as in
physics.
