#4 The Thundercloud That Appears in Australia’s Island Every Afternoon
From September to March, every year, a thundercloud named Hector forms nearly every afternoon on the Tiwi Islands in Australia. Hector, also known as Hector the Convector is known as one of the most consistent thunderstorms. It was named by a pilot during WWII and it still remains the center of many meteorological studies. Though many meteorologists have studied the phenomenon that is Hector, they have not come up with a valid explanation on why the thunderstorm keeps appearing.
