Morphology

cumulonimbus = cumulus + nimbus (transparent) = cumulus + nimbus

The word is a straightforward scientific compound of the two cloud-type nouns 'cumulus' and 'nimbus', so knowing those bases yields the meaning.

Etymology

Cumulonimbus comes from Latin words cumulus ('heap') and nimbus ('rain cloud'), so imagine a huge 'heap' of cloud full of rain. That's why a cumulonimbus is a tall, heavy storm cloud that often brings thunder and lightning.
