· Cyclones- Indian Ocean
· Typhoons- Pacific Ocean

What is a Cyclone?


Hurricanes, Typhoons, and Cyclones are one of nature’s most powerful forces. They are all tropical storms whose winds reach around 74 miles per hour or even more. Their wind blows in a spiral direction around a relatively calm area known as “The Eye”. The eye is usually 20 to 30 miles wide. The most violent activity takes place in the area immediately around the eye, called “The Eyewall”. As the hurricane approaches, the sky begins to darken, and the wind gets stronger. As it nears lands, it may bring torrential rain, storm surges, and very high winds. One hurricane can last for more than 2 weeks in open waters. The heavy rain brought by a hurricane not only threatens coastal areas, but it also hits areas hundreds of miles inland. In some cases, flooding occurs days after a storm actually hits shore.

Months when it occurs include: August and September are the peak months during hurricane season. Hurricane season is between June 1st and November 30th.

The name Hurricane was applied to migratory tropical cyclones. They originate over oceans in certain regions near the equator, and particularly to those arising in the West Indian region, including the Caribbean Sea and the Gulf of Mexico. In the North Pacific and Philippines area are “typhoons” while in the Indian and South Pacific Ocean are “cyclones.”
