What is a hurricane and how does it form?
A hurricane, or tropical cyclone, is a seasonal storm that forms over warm sea water. When sea water warms to a temperature of 26 to 27 degrees Celsius, the water vapor rises, creating a low-pressure area. This causes winds to rotate rapidly, leading to a cyclone. An "eye" forms at the center of the cyclone, which remains relatively calm. The wall surrounding the eye is the most dangerous, as it has the highest wind speeds and heavy rainfall.
Names of Storms and Global Variation
Storms forming in different oceans around the world have different names. Storms that form in the Indian Ocean and the Bay of Bengal are called hurricanes or cyclonic storms in India. Storms that form in the Atlantic Ocean and the eastern Pacific Ocean are called hurricanes, and storms that form in the western Pacific Ocean are called typhoons.
Categories of Storms by Wind Speed The India Meteorological Department (IMD) categorizes storms based on wind speed. If the wind speed is less than 50 kilometers per hour, it is called a depression, which brings light rain. Storms with winds of 50 to 60 kilometers per hour are called deep depressions, which bring heavy rain. A storm with winds of 60 to 90 kilometers per hour is called a cyclonic storm and can cause minor damage.
When winds reach 90 to 120 kilometers per hour, it is called a severe cyclonic storm, which can cause loss of life and property. A storm with winds of 120 to 220 kilometers per hour is called a very severe cyclonic storm and is destructive. A storm with winds of more than 220 kilometers per hour is called a super cyclone, which can be extremely destructive.
How are storms named?
Thirteen countries have formed a panel under the World Meteorological Organization (WMO) to name storms. These include India, Pakistan, Bangladesh, Sri Lanka, Maldives, Myanmar, Thailand, Oman, Iran, Qatar, Saudi Arabia, the United Arab Emirates, and Yemen. These countries jointly prepare a list of names, which is updated every 5–10 years. Currently, the WMO has a list of 169 names.
