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
Cyclogenesis cloud. The wall cloud is a spinning layer of clouds descending from the mesocyclone. The wall cloud tends to form closer to the center of the mesocyclone. It should be noted the wall clouds do not necessarily need a mesocyclone to form and do not always rotate. As the wall cloud descends, a funnel-shaped cloud may form at its center. This is the first stage of tornado formation. The presence of a mesocyclone is believed to be a key factor in the formation of the strong tornadoes associated with severe thunderstorms. Tornadoes exist on the microscale or low end of
