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
Cloud mainly by altitude or level. There are a few species, each of which can be associated with genera of more than one physical form. The species types are grouped below according to the physical forms and genera with which each is normally associated. The forms, genera, and species are listed in approximate ascending order of instability or convective activity. Genus and species types are further subdivided into "varieties" whose names can appear after the species name to provide a fuller description of a cloud. Some cloud varieties are not restricted to a specific altitude level or form, and can therefore
