Question

Quizplus · Accepted Answer

The electrification of a cumulonimbus cloud involves all of the options listed. Graupel or hailstones are important because they can acquire a positive charge as they fall through the negatively charged upper portion of the cloud. Supercooled cloud droplets can also become charged by collisions with graupel or hailstones. Ice crystals may also play a role in the electrification process. Therefore, all three options are necessary for the electrification of a cumulonimbus cloud.
