Hector, or sometimes "Hector the Convector", is known as one of the world's most consistently large thunderstorms, reaching heights of approximately . History. Named by pilots during the Second World War, the recurring position of the thunderstorm made it a navigational beacon for pilots and mariners in the region. Hector is caused primarily by a collision of several sea breeze boundaries across the Tiwi Islands and 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.
