Which one of the following pairs is not correctly matched?

Tropical cyclones are known by various regional names depending on their location. In the China Sea and Western Pacific, they are called Typhoons [4]. In the Gulf of Mexico and the Atlantic, they are referred to as Hurricanes [4]. In North-West Australia, the term Willy-Willies is traditionally used [3]. However, in the Indian Ocean, these storms are simply called Cyclones [4]. Tornadoes are distinct atmospheric phenomena characterized by small-scale, intense vertical vortices that occur primarily over land, such as in the southern USA and West Africa, rather than being the regional name for tropical cyclones in the Indian Ocean [1][t2]. Therefore, the pair 'Indian Ocean : Tornadoes' is incorrectly matched as the correct term for the Indian Ocean is Cyclones.
