Flammagenitus (cloud) large firestorm has been extinguished by the flammagenitus that it created. However, if the fire is large enough, then the cloud may continue to grow, and become a type of cumulonimbus cloud known as a cumulonimbus flammagenitus, which may produce lightning and start another fire. Flammagenitus (cloud) A flammagenitus, also known as a pyrocumulus cloud or fire cloud, is a dense cumuliform cloud associated with fire or volcanic eruptions that may produce dry lightning (lightning without rain). A flammagenitus is similar dynamically in some ways to a firestorm, and the two phenomena may occur in conjunction with each other. However,
Cloud newly formed cloud is determined mainly by air mass characteristics such as stability and moisture content. If these characteristics change over time, the genus tends to change accordingly. When this happens, the original genus is called a "mother cloud". If the mother cloud retains much of its original form after the appearance of the new genus, it is termed a "genitus" cloud. One example of this is "stratocumulus cumulogenitus", a stratocumulus cloud formed by the partial spreading of a cumulus type when there is a loss of convective lift. If the mother cloud undergoes a complete change in genus, it
