Cumulonimbus flammagenitus (cloud) column of a volcano. In 2002, various sensing instruments detected 17 distinct cumulonimbus flammageniti in North America alone. Alternate spellings and abbreviations for cumulonimbus flammagenitus that may be found in the literature include Cb-Fg, pyrocumulonimbus, pyro-cumulonimbus, pyroCb, pyro-Cb, pyrocb, and pyro-cb.

The supercell resulted in a large fire tornado, rated at EF3

Companies can cut costs with cloud communications services without sacrificing features. The success of Google and others as cloud-based providers has demonstrated that a cloud-based platform can be just
