Question

In clouds why are positive charge found upper and negative charge found lower.

Answer 1

Positively charged particles accumulate at the top of the cloud while negatively charged particles concentrate themselves at the bottom of the cloud. ... Once in the cloud the heavier vapor particles have a negative charge and thus sink to the cloud's bottom.

Lighter, positively charged particles form at the top of the cloud. Heavier, negatively charged particles sink to the bottom of the cloud. When the positive and negative charges grow large enough, a giant spark - lightning - occurs between the two chargeswithin the cloud.

This causes the ground and any objects (or people) on the ground directly underneath the storm to become positively charged (Figures 4 and 5). As the negative charge in the cloud increases, the ground responds by becoming more positively charged.

it is not proven yet but yeah many theories regarding this.
