Answer 2

heavy rain fall, snow, lightning, hail

Step-by-step explanation:

Cumulonimbus clouds are considered as thunder storm cloud and thus they bring with them heavy rain fall, snow, lightning, hail and in severe cases they may even cause tornadoes. These clouds are formed very close to the earth’s surface , thus they carry heavy moisture and due to continuous rubbing the droplets in them get ionized which produces lighting as of the static charge.
