  • Why meteorologists are comparing Storm Eowyn to a bomb?

    Why in the News?

    Storm Éowyn has hit the British Isles with very strong winds, especially in Ireland and Scotland.

    What are the meteorological characteristics of Storm Eowyn?

    • Explosive Cyclogenesis: Storm Éowyn qualifies as a “bomb cyclone,” with air pressure at its center dropping 50 millibars within 24 hours, significantly exceeding the 24-millibar threshold for explosive cyclogenesis. This rapid deepening is a hallmark of severe winter storms in the region.
    • Wind Speeds: The storm produced wind gusts exceeding 100 mph, with a record gust of 114 mph reported at Mace Head on Ireland’s west coast. The Met Office issued red warnings for widespread gusts of 80-90 mph, particularly affecting Northern Ireland and central and southern Scotland.
    • Jet Stream Influence: A strong jet stream, with winds exceeding 200 mph, played a crucial role in the storm’s development. The temperature contrast between cold air from the eastern US and warmer air over the North Atlantic contributed to this intensity.

    What impacts it had on affected regions and what are the expected consequences?

    • Power Outages and Damage: Nearly one million properties across the British Isles experienced power outages due to downed trees and damaged infrastructure. Restoration efforts are expected to take several days, with some areas potentially facing up to ten days without power.
    • Transport Disruptions: The storm caused significant disruptions to road and rail services, with many routes blocked or cancelled due to hazardous conditions. Emergency services have been deployed to manage the aftermath.
    • Casualties: Tragically, at least one fatality was reported in Ireland when a tree fell on a vehicle due to the high winds. The overall impact of the storm has raised concerns about safety and emergency preparedness in affected regions.

    How does Storm Eowyn fit into broader climate change trends and patterns of extreme weather events?

    • Climate Change Considerations: While Storm Éowyn’s intensity raises questions about climate change’s role in extreme weather events, current research has not conclusively linked specific storm intensities or frequencies to climate change.
      • The Intergovernmental Panel on Climate Change (IPCC) reports low confidence in observed trends related to extratropical storms over the last century.
    • Future Storm Patterns: There are indications that future winter storms may become more frequent and clustered, leading to increased overall impacts. Additionally, as global temperatures rise, storms may exhibit more extreme wind speeds and rainfall due to a warmer atmosphere’s capacity to hold more moisture.
    • Potential for Sting Jets: There is speculation that Storm Éowyn may have developed “sting jets,” which can produce localized but extremely destructive winds. While their occurrence is difficult to predict, studies suggest that such phenomena may increase with future cyclones as atmospheric conditions evolve.

    Way forward: 

    • Strengthening Infrastructure & Emergency Preparedness – Governments should invest in resilient power grids, reinforced transportation networks, and improved early warning systems to mitigate the impact of extreme storms.
    • Climate Adaptation & Policy Measures – Policymakers should integrate climate resilience into urban planning, enforce stricter building codes, and invest in sustainable land management to reduce vulnerabilities.

  • Earth’s magnetic North Pole is shifting toward Siberia

    Why in the News?

    Earth’s magnetic north pole, a critical point where the planet’s magnetic field lines converge, is in constant motion due to changes in the Earth’s molten core. Currently located in the Arctic Ocean above Canada, the magnetic north pole has been moving towards Siberia at an accelerated pace.

    What is the World Magnetic Model (WMM)?

    • The WMM is the standard model used for navigation, attitude, and heading referencing systems that rely on Earth’s geomagnetic field.
    • It is widely used in civilian applications, including navigation and heading systems, as well as in military operations.
    • The WMM provides accurate data on the Earth’s magnetic field and the location of the magnetic North Pole, combining measurements from ground stations and satellites.
    • Revisions and Updates:
      • A new version is updated every five years to address changes in the magnetic field.
      • The latest version, WMM2025, was released on December 17, 2024, and will remain valid until late 2029.
    • The WMM is jointly developed by the United States’ National Geospatial-Intelligence Agency (NGA) and the United Kingdom’s Defence Geographic Centre (DGC), with technical support from NCEI and the British Geological Survey (BGS).
    • It serves both civilian and military purposes, ensuring accuracy in navigation systems, GPS applications, and other tools dependent on Earth’s magnetic field.

    Why is the Magnetic North Pole Moving?

    • The magnetic North Pole moves due to the dynamic flow of molten iron and other metals in Earth’s outer core, which generates the planet’s magnetic field.
    • These movements cause shifts in magnetic field lines, leading to the pole’s drift over time.
    • The pole was first identified in Canada in 1831 and has since moved over 400 km toward Russia.
    • Key Observations of Movement:
      • From 1990 to 2000, the pole drifted at a rapid rate of 55 km/year.
      • By 2015, this rate slowed to 35 km/year, but the drift remains unpredictable.
      • Currently, the pole is moving closer to Siberia, reflecting changes in Earth’s core dynamics.
    • Impact of Movement:
      • The drift affects navigation systems, aviation routes, and Earth’s magnetic shielding against harmful solar radiation.
      • Scientists monitor this movement using the WMM to ensure updated predictions and mitigate potential impacts on navigation and environmental protection.

  • Can Bhopal waste be safely disposed of?

    Why in the News?

    The Madhya Pradesh High Court gave authorities four weeks to dispose of the waste, nearly 40 years after the gas disaster that killed over 4,000 people and left thousands more injured or disabled.

    What are the plans for the hazardous gas leak waste? 

    • Waste Transportation: The Madhya Pradesh government has successfully transported 358 tonnes of hazardous waste from the Union Carbide facility in Bhopal to the Treatment, Storage, and Disposal Facility (TSDF) in Pithampur, Dhar district, following a court order.
    • Incineration Process: The waste will be incinerated at the Pithampur facility, with an initial timeline of three to nine months for complete disposal, depending on emissions and safety assessments during the process.
    • Emission Controls: To mitigate air pollution, the incinerator will utilize four-layer special filters to ensure that the smoke emitted does not contaminate the surrounding environment.
    • Post-Incineration Measures: After incineration, the resulting ash will be covered with a two-layer membrane and buried in a landfill to prevent any contact with soil and water sources.
    • Expert Supervision: The entire disposal process will be overseen by officials from the Central Pollution Control Board and State Pollution Control Board, ensuring compliance with safety regulations and environmental standards.

    How much has been allocated to incinerate the waste and deposit the residue at a landfill in Pithampur?

    • The Central government has allocated ₹126 crore (approximately $15 million) to facilitate the incineration of this waste and ensure that any resulting residue is safely deposited in a landfill at the Pithampur facility.

    Why have there been protests?

    • Health and Environmental Fears: Residents are worried that the incineration of toxic waste will pose significant health risks and environmental hazards to the local population and surrounding areas, with claims that it could lead to harmful emissions affecting air quality.

  • Need quake warning systems: PM; working to better accuracy by 10-15%, says IMD DG

    Why in the News?

    Recently, PM released the IMD’s Vision Document 2047, outlining a plan to achieve nearly perfect weather forecasts for up to three days and 90% accuracy for forecasts made five days ahead by 2047.

    What is IMD’s Vision Document 2047? 

    • The Vision Document aims for zero-error forecast accuracy for up to three days lead time and 90% accuracy for forecasts issued five days in advance by 2047. This ambitious target reflects India’s commitment to improving weather forecasting capabilities significantly.
    • Focus Areas: The document emphasises enhancing weather surveillance technologies, improving atmospheric observations, and leveraging high-performance computing systems.
      • It also highlights the importance of developing advanced earth system models and data-driven methods, including the use of AI and machine learning.

    Why does India need an Earth warning system? 

    • High Seismic Vulnerability: India lies in a seismically active zone, with regions like Himachal Pradesh, Uttarakhand, and the Northeast being particularly earthquake-prone. Early warning systems can help reduce damage and save lives in these areas. Example: The 2001 Gujarat earthquake caused widespread devastation.
    • Risk to Dense Urban Areas: Major cities like Delhi, Mumbai, and Kolkata are vulnerable to earthquakes. Early warnings can help evacuate people, protect infrastructure, and minimize casualties. Example: A strong earthquake in Delhi could severely impact millions.
    • Limited Preparedness and Response Time: Earthquakes give little to no time for people to react. A warning system could provide crucial seconds or minutes to activate emergency protocols, limiting loss of life and property. Example: The 2015 Nepal earthquake caused devastation in northern India.

    How can India achieve zero-error accuracy in forecasting disasters?

    • Technological Advancements: The implementation of Mission Mausam involves deploying next-generation radars, satellites with advanced instruments, and high-performance computing systems. These tools are crucial for improving the precision of weather predictions.

    • Capacity Building: The initiative will also focus on building capacity within meteorological services to ensure that no severe weather events go undetected. This includes training personnel and enhancing operational frameworks for the timely dissemination of forecasts.

    What are the steps taken by the Indian Government in the past year?

    • Amendment of the Disaster Management Act: In August 2024, the government introduced the Disaster Management (Amendment) Bill, 2024, in the Lok Sabha.
      • This bill proposes the establishment of Urban Disaster Management Authorities for state capitals and large cities, the creation of disaster databases at national and state levels, and the formation of State Disaster Response Forces to strengthen disaster response capabilities.
    • Investment in Urban Flood Mitigation: In August 2024, India announced plans to invest nearly $300 million over two years to mitigate urban flooding and conserve water in major cities, including Mumbai, Chennai, and Bengaluru.
      • The initiative focuses on expanding water bodies like lakes and constructing drainage systems to manage excessive rainfall during monsoon seasons.
    • Addressing Urban Heat Islands: In June 2024, government officials acknowledged that rapid urbanization has turned cities into “heat traps,” exacerbating the effects of heatwaves.
      • Efforts are underway to implement heat action plans, which include provisioning drinking water, improving medical facilities, rescheduling outdoor work, and increasing green spaces to mitigate urban heat.
    • Enhancement of Early Warning Systems: The government has been working to improve early warning systems for various natural disasters, including floods and heatwaves, to provide timely alerts and reduce the impact on vulnerable populations.
    • Capacity Building and Training: There has been a focus on training and capacity building for disaster response teams at both national and state levels. For instance, In 2024, the NDRF organised a multi-agency mock drill in Assam to simulate a response to a major flood disaster.

    What are the challenges in forecasting a disaster?

    • Data Gaps and Limited Technology: Forecasting requires high-quality, real-time data from advanced technologies like satellite imagery, weather radars, and seismic sensors. However, data scarcity in remote areas or regions with underdeveloped infrastructure hampers accurate predictions.
      • Example: The 2013 Kedarnath floods in India resulted from a cloudburst that was not forecasted in time due to a lack of localized meteorological data and advanced radar systems.
    • Unpredictability of Natural Phenomena: Some disasters, such as earthquakes and tsunamis, are inherently unpredictable because they result from sudden geological shifts.
      • Example: The 2004 Indian Ocean tsunami followed a massive earthquake, but the lack of a regional tsunami warning system in the Indian Ocean made it impossible to alert affected countries in time.
    • Challenges in Communication and Dissemination: Even when forecasts are accurate, ineffective communication of warnings to vulnerable populations due to language barriers, poor outreach, or lack of awareness can render forecasts ineffective.
      • Example: During Cyclone Tauktae (2021) in India, while the forecast was accurate, several fishermen ignored warnings to evacuate, leading to fatalities despite advanced cyclone prediction systems.

    Way forward: 

    • Strengthen Technological and Data Capabilities: Invest in localized weather stations, advanced radar systems, and seismic sensors in remote areas, while leveraging AI and machine learning for precise forecasting and real-time data integration.
    • Enhance Community Awareness and Communication: Develop multilingual, accessible early warning systems and conduct regular public awareness campaigns to ensure timely dissemination and community readiness during disasters.
