Hurricanes, Tropical Cyclones and Typhoons

What is a tropical cyclone?

A tropical cyclone is a type of large storm system having a circular or spiral system of violent winds, typically hundreds of kilometers or miles in diameter. The winds spiral around a region of low atmospheric pressure. "Tropical Cyclone" is the name given to these storms when they occur in the Indian Ocean. "Hurricane" is the name given to these storms in the Atlantic Ocean and Eastern Pacific. Similar storms that occur in the Western Pacific are called "Typhoons".

What is a typhoon?

A typhoon is a type of large storm system having a circular or spiral system of violent winds, typically hundreds of kilometers or miles in diameter. The winds spiral around a region of low atmospheric pressure. "Typhoon" is the name of these storms that occur in the Western Pacific. "Hurricane" is the name given to these storms in the Atlantic Ocean and Eastern Pacific. In the Indian Ocean, they are called "Tropical Cyclones".

What is the Saffir-Simpson scale?

In 1972, American scientists Herbert Saffir and Robert Simpson developed the Saffir-Simpson Scale to classify the severity of hurricanes. This scale ranks hurricanes by the intensity of wind speeds. Hurricanes are divided into five categories, as described in the table below:

How many hurricanes have been in existence at once?

Four. In 1998, four hurricanes were observed in the Atlantic at the same time. This event had not occurred since 1893. These four hurricanes were Ivan, a Category 1 storm; Jeanne and Karl, which were Category 2 storms; and Georges, a Category 4 storm. They were in existence largely during the middle to the end of September, 1998.

When is a hurricane/tropical storm warning put into effect for a specific region?

A hurricane/tropical storm watch is put into place when it is possible for tropical storm conditions to hit the region within 24 hours.

When is a hurricane/tropical storm watch put into effect for a specific region?

A hurricane/tropical storm watch is put into place when it is possible for tropical storm conditions to hit the region within 36 hours.

What is a storm surge?

A storm surge is a wall of water pushed onshore by the winds of hurricanes and other tropical storms. Storm surges can be as high as 7.5 m. (25 ft.) and as wide as 60 km (100 miles).
