Introduction:
A storm occurs when there are strong winds caused by changes in the air pressure in the atmosphere. These changes in air pressure can lead to very bad weather, including heavy rain, thunder, and powerful winds.
A storm
Causes and Effects
Causes:
- Air Pressure Changes: Storms are caused by the formation of high- and low-pressure belts in the atmosphere. When there is a big difference between high and low pressure, strong winds are created.
- Wind Movement: These winds move very quickly from high-pressure areas to low-pressure areas, which results in a storm.
Effects:
- Damage to buildings
- Falling trees
- Loss of life
- Power outages
- Flooding
- Disruption of transport
- Communication breakdown
- Economic losses
Prevention and Safety Measures:
- Trim trees to prevent branches from falling.
- If outside, find shelter in a safe place.
- Inform relatives and friends of your location if you are away from home.
- Turn off gas valves and electricity at home to avoid fires.
- Warn others about the storm and tell them to move to a safer place.
- Provide temporary shelter to those stranded far from their homes.
National Institutions:
United Nations Development Programme (UNDP): Established in 1965 to help countries during disasters. 177 nations are members of the UNDP.
UNDP sends:
- Equipment and financial aid to disaster-hit areas.
- Volunteers, medical teams, and experts to help people.
13th October is celebrated as the International Day for Disaster Reduction to raise awareness.
