Hint: These clouds can extend high into the atmosphere, sometimes reaching the stratosphere, and are known for their dense, anvil-shaped tops.

Cumulonimbus clouds are towering vertical clouds that are often associated with thunderstorms and severe weather.

These clouds can extend high into the atmosphere, sometimes reaching the stratosphere, and are known for their dense, anvil-shaped tops.

Cumulonimbus clouds form when warm, moist air rises rapidly, cools, and condenses into water droplets. As the cloud grows, it can produce intense rain, lightning, thunder, and even tornadoes. The presence of a cumulonimbus cloud is a strong indicator of unstable atmospheric conditions, making it a key feature in weather forecasting and storm prediction.
