What Are Some Facts About Typhoons?

What are some facts about typhoons?  Typhoons are just like hurricanes but they occur in a different place.  Hurricanes occur in the North Atlantic Ocean, the Northeast Pacific Ocean east of the dateline, and the South Pacific east of 160E.  Typhoons occur in the Northwest Pacific Ocean west of the date line. The word “typhoon” is taken from the Cantonese word "tai feng."   

The first facts about typhoons deal with the rating scale for typhoons:

  • Once a tropical storm has reached sustained winds of 74 miles per hour or 64 knots per hour, the storm is classified a typhoon. 
  • After that, there are only two divisions: severe typhoon and super typhoon. 
  • A severe typhoon has sustained winds of at least 80 knots or 95 miles per hour and a super typhoon has sustained winds of at least 100 knots or 115 miles per hour. 
  • In summary, a severe typhoon’s winds would be between 80 and 99 knots and a super typhoon’s winds would be 100 knots or more.

Formation of Typhoons

Here are some facts about typhoon's formations:

  • Typhoons begin over warm water and in humid air between 10 and 20 degrees latitude north in the Pacific Ocean. 
  • As warm air rises from the surface of the water, less air is left and a low pressure area develops. 
  • This area of low pressure pulls in the air around it. 
  • As the air comes in, it warms up and begins to rise. 
  • Clouds begin to form as the air cools because of its elevation and soon the system begins to rotate. 
  • If conditions are favorable, especially the temperature of the water, then the system grows and eventually an eye will form. 
  • If the water temperature drops below 79 degrees Fahrenheit, the storm will weaken. 
  • It will also dissipate if it moves over land.  When the winds become 74 miles per hour, it is classified a typhoon. 

More Facts About Typhoons

Here are a few miscellaneous facts about typhoons:

  • Some of the countries that experience typhoons: Guam, Marianas Islands, Philippines, Taiwan, southern China, South Korea, southern Japan, and Vietnam. 
  • Before a typhoon hits, there are large waves, falling barometric pressure, and a storm surge. 
  • As it is getting nearer, the winds will get stronger and huge amounts of cumulus clouds appear. 
  • When the typhoon hits, there will be torrential rains and high winds. 
  • Typhoons and hurricanes in the northern Hemisphere spin in a counter clockwise direction. 
  • The eye of the storm can be between 5 and 25 miles wide. 

Deadliest Typhoons

Here are the facts about the five deadliest typhoons with the year and the number of fatalities: 

  • Great Bhola, Bangladesh - 1970 - 500,000
  • Hooghly River, India and Bangladesh - 1737 - 300,000
  • Haiphong, West Pacific - 1881 - 300,000
  • Coringa, India - 1839 - 300,000
  • Backerganj, Bangladesh - 1876 - 200,000

Things to Do During a Typhoon 

Here are the straight facts of what to do if a typhoon is approaching your home: 

  • Secure your property by bring indoors things that could blow away or cause damage to the house, like furniture, bicycles, or plants.
  • Fasten windows securely and board them if there is time.  
  • Obtain extra water and extra food that does not need to be cooked in case there is no power.
  • Turn down the setting on your freezer to the coldest setting to help keep food from spoiling in case the electricity is cut off.
  • Have towels, mops, and rags ready and watch for leaks around doors and windows.
  • Draw all the curtains to minimize damage from broken glass and open a window slightly that is on the side of the house that is away from the approaching storm.
  • If the storm is very strong, move into an interior room or hallway away from windows. 
  • Remember that typhoons have eyes so there may be a period of time when the weather is calm and then the winds will pick up again. 

So, now you know lots of facts about typhoons.
