About Thunderstorm

• A thunderstorm is a weather phenomenon involving lightning, thunder, strong winds, heavy rainfall and sometimes hail.
• Key Features
  • Strong Convective Activity: Thunderstorms develop due to rapid upward movement of warm and moist air.
  • Lightning and Thunder: Electrical discharge within clouds produces lightning and the associated sound known as thunder.
  • Gusty Winds: Severe thunderstorms generate powerful winds capable of uprooting trees and damaging infrastructure.
  • Short Duration but High Intensity: Thunderstorms usually last for a short period but can cause significant destruction locally.
• Different Factors Responsible for Thunderstorm
  • Intense Surface Heating: High pre-monsoon temperatures create warm air near the surface that rises rapidly.
  • Moisture Incursion: Moisture-laden winds from the Bay of Bengal provide energy for cloud formation and storm development.
  • Western Disturbances: Western disturbances bring cool and dry upper-level air that increases atmospheric instability.
  • Atmospheric Instability: The interaction of warm moist air below and cool dry air above creates conditions favourable for severe thunderstorms.
• Impact of Thunderstorm
  • Loss of Human Lives: Lightning strikes, collapsing structures and flying debris cause fatalities and injuries.
  • Infrastructure Damage: Strong winds damage electricity poles, roads, buildings and communication systems.
  • Agricultural Losses: Heavy rain, hailstorms and winds damage standing crops and orchards.
  • Transport and Power Disruptions: Thunderstorms disrupt road transport, railways, aviation services and electricity supply.

NDMA Guidelines for Thunderstorm

• Before Thunderstorm
  • Monitor Weather Alerts: Follow advisories issued by the India Meteorological Department and local authorities.
  • Secure Loose Objects: Fasten outdoor items such as hoardings, metal sheets and containers to prevent accidents.
  • Prepare Emergency Supplies: Keep torches, batteries, medicines, drinking water and emergency contact numbers ready.
• During Thunderstorm
  • Stay Indoors: Remain inside a strong building and avoid open fields, trees and water bodies.
  • Avoid Electrical Appliances: Disconnect electronic devices and avoid using wired communication equipment.
  • Follow Lightning Safety: Avoid taking shelter under isolated trees and stay away from metal objects.
• After Thunderstorm
  • Check for Injuries and Damage: Provide first aid and inform emergency authorities about casualties and damaged infrastructure.
  • Avoid Fallen Power Lines: Stay away from broken electric poles and exposed wires to prevent electrocution.
  • Ensure Safe Movement: Travel only after authorities declare roads and public areas safe.
