Thunderhead.pdf (2025)

A Thunderhead, also known as a Cumulonimbus cloud, is a type of cloud that can reach heights of over 10,000 meters (33,000 feet). It is a dense, towering cloud with a flat base and a distinctive anvil-shaped upper surface. Thunderheads are formed when warm, moist air rises rapidly into cold air, creating towering clouds with strong updrafts and downdrafts.
