FAQs on Tropical Cyclone Video Lecture - Geography for UPSC CSE

1. What are the different categories of tropical cyclones?
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.
2. How do tropical cyclones form?
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.
3. What is the difference between a hurricane, cyclone, and typhoon?
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.
4. What are the typical effects of a tropical cyclone?
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.
5. How can individuals prepare for a tropical cyclone?
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.
