What cloud is an example of a pyrocumulus cloud?

Definition: A fire-caused cumulus or cumulonimbus cloud better known as a pyrocumulus cloud.

What do pyrocumulus clouds do?

In a pyrocumulus cloud, the hot air cools and then condenses very efficiently using smoke particles from the fire below as cloud condensation nuclei. The rapidly rising motion and development of these clouds can not only produce rain, but also lightning and thunder.

What is a pyrocumulus cloud collapse?

Pyrocumulus clouds typically reach 20 to 40 thousand feet above the earth. Turbulence in the atmosphere causes cooler air to mix into the plume. When it reaches high enough, lower air pressure will cause it to cool and form a cloud. Water vapor condenses and causes rapid cooling which creates down-bursts.

Do pyrocumulus clouds burn?

On this fire, crews are seeing the biggest and most dangerous clouds over a section of wilderness that’s made up mostly of dead trees, which burn instantly and with a lot of heat.

Is it possible to rain fire?

A flammagenitus cloud can help or hinder a fire. Sometimes, the moisture from the air condenses in the cloud and then falls as rain, often extinguishing the fire. There have been numerous examples where a large firestorm has been extinguished by the flammagenitus that it created.

How do you say pyrocumulus?

What is the difference between a thunderstorm cumulonimbus and a pyrocumulus?

A pyrocumulonimbus cloud, or “fire storm cloud,” may form when a fire is big and intense enough. Thunderstorm clouds are called cumulonimbus clouds — the nimbus part of the name comes from the Latin for “dark cloud,” because the moisture within nimbus clouds can block or reduce incoming sunlight.

Can a drop of water start a fire?

“If the focal region of drops falls exactly on the dry plant surface intensely focused sunlight could theoretically start a fire,” Horvath said. “However, the likelihood is reduced as the water drops should evaporate before this, so these claims should be treated with a grain of salt.”

What is the difference between a thunderstorm cumulonimbus and a Pyrocumulus?
