Hector (cloud) is known for its consistency and intensity. Lightning rates and updraft speeds are notable aspects of this thunderstorm and during the 1990s National Geographic Magazine published a comprehensive study of the storm with pictures of damaged trees and details of updraft speeds and references to tornadic events. Since the late 1980s the thunderstorm has been the subject of many meteorological studies, many centred on Hector itself but also utilising the consistency of the storm cell to study other aspects of thunderstorms and lightning. Hector (cloud) Hector is the name given to a cumulonimbus, or thundercloud, that forms regularly nearly every
Flammagenitus (cloud) 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, either may occur without the other. A flammagenitus cloud is produced by the intense heating of the air from the surface. The intense heat induces convection, which causes the air mass to rise to a point of stability, usually in the presence of moisture. Phenomena
