FAQs on Tropical Cyclone

Question 1

1. What are the different categories of tropical cyclones?

Accepted Answer

Ans.Tropical cyclones are classified into five categories based on their maximum sustained wind speeds. These are: - Category 1: Winds of 74-95 mph (119-153 km/h)- Category 2: Winds of 96-110 mph (154-177 km/h)- Category 3: Winds of 111-129 mph (178-208 km/h)- Category 4: Winds of 130-156 mph (209-251 km/h)- Category 5: Winds exceeding 157 mph (252 km/h). Each category indicates the potential damage and severity of the cyclone.

Question 2

2. How do tropical cyclones form?

Accepted Answer

Ans.Tropical cyclones form over warm ocean waters, typically when sea surface temperatures exceed 26 degrees Celsius (79 degrees Fahrenheit). They require a pre-existing weather disturbance, moist air, and low vertical wind shear to develop. The warm, moist air rises, creating a low-pressure area, and as more air is drawn in, it begins to rotate due to the Coriolis effect, leading to the formation of a cyclone.

Question 3

3. What is the difference between a hurricane, cyclone, and typhoon?

Accepted Answer

Ans.Hurricanes, cyclones, and typhoons are all names for the same weather phenomenon, which is a tropical cyclone. The term used depends on the location:- 'Hurricane' is used in the Atlantic and Northeast Pacific.- 'Typhoon' is used in the Northwest Pacific.- 'Cyclone' is used in the South Pacific and Indian Ocean.Despite the different names, they exhibit similar characteristics and behaviors.

Question 4

4. What are the typical effects of a tropical cyclone?

Accepted Answer

Ans.The effects of a tropical cyclone can be devastating and may include:- Strong winds that can cause structural damage to buildings and infrastructure.- Heavy rainfall leading to flooding and landslides.- Storm surges that can inundate coastal areas.- Displacement of communities and destruction of habitats.The severity of these effects depends on the cyclone's category and the area it impacts.

Question 5

5. How can individuals prepare for a tropical cyclone?

Accepted Answer

Ans.Preparation for a tropical cyclone involves several steps:- Stay informed by monitoring weather updates and warnings from local authorities.- Create an emergency kit with essentials such as food, water, medications, and a flashlight.- Develop a family emergency plan that includes evacuation routes and communication methods.- Secure your property by reinforcing windows and doors and clearing outdoor items that could become projectiles.- Follow evacuation orders and seek shelter if necessary to ensure safety during the storm.
