Cumulonimbus Clouds Next Topic: Cumulus Clouds

The final form taken by a growing cumulus cloud is the cumulonimbus cloud, which is very tall and dense. The tower of a cumulonimbus cloud can soar 23 km into the atmosphere, although most commonly they stop growing at an altitude of 6 km.

Even small cumulonimbus clouds appear very large in comparison to other cloud types. They can signal the approach of stormy weather, such as thunderstorms or blizzards.

Drizzle Next Topic: Evaporation

Drizzle is precipitation in the form of water droplets which are smaller than raindrops.

Drizzle is characterized by fine, gently falling droplets and typically does not impact human habitation in a negative way. The exception to this is freezing drizzle, a condition where drizzle freezes immediately upon reaching earth's surface. Freezing drizzle is still less dangerous than freezing rain, but can potentially result in hazardous road conditions.
