About Typhoon 

  • 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.
