why do clouds have negative charge?

Expert Answer:

There is a difference in pressure and temperature between the different parts of the atmosphere . This results in a constant motion of air packets. The upper atmosphere is very cool, so water vapors condense to form small water droplets ( clouds). Due to friction from winds, the clouds get electrically charged.

And, during storms generally the upper part gets positively charged while the lower parts get negatively charged.
