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
Cumulus humilis cloud Cumulus humilis cloud Cumulus humilis are cumuliform clouds with little vertical extent, common in the summer, that are often referred to as "fair weather cumulus". If they develop into cumulus mediocris or cumulus congestus, thunderstorms could form later in the day. They generally form at lower altitudes (500–3000 m (1,500–10,000 ft)), but in hot countries or over mountainous terrain these clouds can occur at an altitude of up to . They show no significant vertical development, indicating that the temperature in the atmosphere above them either drops off very slowly or not at all with altitude; that is, the adiabatic
