Typhoon and hurricane are two of the regionally specific names for strong tropical cyclones
Tropical cyclones are rotating, organized systems of clouds and thunderstorms that originate over tropical or subtropical waters and have closed, low-level circulation.
What a tropical cyclone gets called is determined by the ocean it forms over and how severe it becomes.
In the North Atlantic, central North Pacific, and eastern North Pacific, tropical cyclones are called hurricanes.
In the Northwest Pacific, they are known as typhoons.
Super Typhoon
Since 2009 the Hong Kong Observatory has divided typhoons into three different classifications: typhoon, severe typhoon and super typhoon.
A typhoon has wind speed of 118–149 km/h, a severe typhoon has winds of at least 150 km/h, and a super typhoon has winds of at least 190 km/h.
