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?
