Cyclone Michaung, previously known as Cyclone Ditwah, has brought torrential rainfall to Tamil Nadu, resulting in three fatalities and widespread damage to agricultural crops. The India Meteorological Department (IMD) had issued warnings, and the cyclone is expected to intensify further, moving towards the Andhra Pradesh coast.
This event highlights the vulnerability of coastal regions to extreme weather events and the critical need for effective disaster preparedness and management strategies. The state government is assessing the damage and taking measures to provide relief.

Background
Tropical cyclones are among the most destructive natural disasters, particularly for coastal regions. India, with its long coastline, is highly vulnerable to these events, especially those originating in the Bay of Bengal.
The India Meteorological Department (IMD) plays a crucial role in forecasting and issuing warnings, which are vital for disaster preparedness and mitigation. Over the years, India has significantly improved its early warning systems and disaster response mechanisms, yet challenges persist, exacerbated by climate change.

Practice Questions (MCQs)
1. Consider the following statements regarding Cyclone Michaung and related phenomena: 1. Cyclone Michaung originated in the Arabian Sea and is expected to make landfall on India's west coast. 2. The India Meteorological Department (IMD) is the primary agency responsible for issuing cyclone warnings in India. 3. The naming of tropical cyclones in the Indian Ocean region follows a system adopted by the World Meteorological Organization (WMO) and ESCAP panel.
- A.1 and 2 only
- B.2 and 3 only
- C.1 and 3 only
- D.1, 2 and 3
Show Answer
Answer: B
Statement 1 is incorrect. Cyclone Michaung originated in the Bay of Bengal and is moving towards the Andhra Pradesh coast (East coast). Statement 2 is correct; IMD is the nodal agency for meteorological observations and warnings. Statement 3 is correct; the WMO/ESCAP Panel on Tropical Cyclones is responsible for naming cyclones in the North Indian Ocean basin.
2. Which of the following conditions is/are essential for the formation and intensification of a tropical cyclone? 1. Large sea surface with temperature higher than 27°C. 2. Presence of Coriolis force. 3. Small variations in the vertical wind speed. 4. Pre-existing weak low-pressure area or low-level cyclonic circulation.
- A.1, 2 and 3 only
- B.2, 3 and 4 only
- C.1, 3 and 4 only
- D.1, 2, 3 and 4
Show Answer
Answer: D
All four conditions are essential for the formation and intensification of a tropical cyclone. High sea surface temperature provides the necessary latent heat. Coriolis force is crucial for the rotation of the storm. Low vertical wind shear (small variations in vertical wind speed) allows the storm to grow vertically without being torn apart. A pre-existing low-pressure system acts as a 'seed' for the cyclone to develop.
3. In the context of disaster management in India, consider the following statements: 1. The National Disaster Management Authority (NDMA) is headed by the Union Home Minister. 2. The Disaster Management Act, 2005, provides for the constitution of National Disaster Response Force (NDRF) for specialist response to disaster situations. 3. The Sendai Framework for Disaster Risk Reduction (2015-2030) emphasizes a shift from disaster response to disaster risk reduction.
- A.1 and 2 only
- B.2 and 3 only
- C.1 and 3 only
- D.1, 2 and 3
Show Answer
Answer: B
Statement 1 is incorrect. The National Disaster Management Authority (NDMA) is headed by the Prime Minister of India. Statement 2 is correct; the DM Act 2005 legally mandated the creation of NDRF. Statement 3 is correct; the Sendai Framework, adopted in 2015, focuses on understanding disaster risk, strengthening disaster risk governance, investing in disaster risk reduction, and enhancing disaster preparedness for effective response and 'Build Back Better' in recovery, rehabilitation and reconstruction.
4. Which of the following statements correctly describes the 'eye' of a tropical cyclone?
- A.It is the region of strongest winds and heaviest rainfall, surrounding the central calm area.
- B.It is a relatively calm, clear area at the center of the cyclone, characterized by light winds and descending air.
- C.It is the outermost band of clouds and thunderstorms, where winds are moderate.
- D.It is the area where the cyclone first makes contact with land, experiencing maximum storm surge.
Show Answer
Answer: B
The 'eye' of a tropical cyclone is indeed a relatively calm, clear area at the center, characterized by light winds and descending air. Option A describes the eyewall, which surrounds the eye. Options C and D describe other parts or effects of a cyclone, not specifically the eye.
