सारांश
Sri Lanka is grappling with the aftermath of Cyclone Michaung, which caused widespread devastation, including extensive damage to infrastructure, homes, and agricultural land. The cyclone brought heavy rains, strong winds, and flooding, displacing thousands and disrupting essential services.
Authorities are now engaged in relief efforts and assessing the full economic cost of the disaster. Essentially, this event serves as a stark reminder of the increasing frequency and intensity of extreme weather events due to climate change, emphasizing the critical importance of effective disaster preparedness, early warning systems, and resilient infrastructure for vulnerable nations.
पृष्ठभूमि
Tropical cyclones are a recurring feature in the Indian Ocean, particularly the Bay of Bengal, during pre-monsoon (April-June) and post-monsoon (October-December) seasons. Sri Lanka, being an island nation, is highly vulnerable to such events.
Historical records show numerous devastating cyclones affecting the island, necessitating robust disaster management frameworks. The increasing frequency and intensity of these events are often linked to climate change and warming ocean waters, posing significant challenges to vulnerable nations.

बहुविकल्पीय प्रश्न (MCQ)
1. Consider the following statements regarding tropical cyclones in the Indian Ocean region: 1. Tropical cyclones in the Bay of Bengal are generally more frequent and intense than those in the Arabian Sea. 2. The naming of cyclones in the North Indian Ocean is done by a panel of countries, including India, Sri Lanka, and Bangladesh. 3. Cyclone Michaung, which recently affected Sri Lanka, was classified as a 'Very Severe Cyclonic Storm' by the India Meteorological Department (IMD). Which of the statements given above is/are correct?
- A.1 and 2 only
- B.2 and 3 only
- C.1 and 3 only
- D.1, 2 and 3
उत्तर देखें
सही उत्तर: D
Statement 1 is correct: The Bay of Bengal experiences a higher frequency and intensity of tropical cyclones due to warmer sea surface temperatures, higher rainfall, and specific atmospheric conditions. Statement 2 is correct: The naming of tropical cyclones in the North Indian Ocean is done by the Regional Specialized Meteorological Centre (RSMC) New Delhi, which is part of the World Meteorological Organization (WMO)/ESCAP Panel on Tropical Cyclones. This panel comprises 13 member countries: Bangladesh, India, Iran, Maldives, Myanmar, Oman, Pakistan, Qatar, Saudi Arabia, Sri Lanka, Thailand, United Arab Emirates, and Yemen. Statement 3 is correct: Cyclone Michaung was indeed classified as a 'Very Severe Cyclonic Storm' by the IMD before its landfall.
2. In the context of disaster preparedness and management in India, which of the following statements is NOT correct?
- A.The National Disaster Management Authority (NDMA) is chaired by the Prime Minister of India.
- B.The Disaster Management Act, 2005, provides for the constitution of the National Disaster Response Force (NDRF).
- C.The State Disaster Response Fund (SDRF) is the primary fund available with State Governments for immediate relief in case of notified disasters.
- D.The Sendai Framework for Disaster Risk Reduction (2015-2030) is a legally binding international agreement on disaster risk reduction.

सही उत्तर: D
Statements A, B, and C are correct. The NDMA is indeed chaired by the Prime Minister. The DM Act, 2005, established the NDRF. The SDRF is the primary fund for states for immediate relief. Statement D is NOT correct. The Sendai Framework for Disaster Risk Reduction (2015-2030) is a voluntary, non-binding agreement that outlines targets and priorities for action to prevent new and reduce existing disaster risks. It is not legally binding.
3. Which of the following factors is/are considered crucial for the intensification of a tropical cyclone? 1. High sea surface temperatures (above 26.5°C) 2. Low vertical wind shear 3. Pre-existing low-pressure area or disturbance 4. Presence of strong upper-level divergence Select the correct answer using the code given below:
- A.1 and 3 only
- B.2 and 4 only
- C.1, 2 and 3 only
- D.1, 2, 3 and 4
उत्तर देखें
सही उत्तर: D
All four statements are crucial factors for the intensification of a tropical cyclone. High sea surface temperatures provide the necessary energy (latent heat) for convection. Low vertical wind shear allows the storm to maintain its vertical structure and prevents it from being torn apart. A pre-existing low-pressure area or disturbance acts as the 'seed' for cyclone formation. Strong upper-level divergence helps to ventilate the storm, allowing more air to rise from the surface and thus intensifying the low-pressure system at the surface.
