What is a tornado ?
Tornadoes: A tornado is a dark funnel shaped cloud that reaches from the sky to the ground Most of the tornadoes are weak. A violent tornado can travel at speeds of about 300 km/h. Tornadoes may form within cyclones. In our country Tornadoes are not very frequent.

What is a Tornado?
A tornado is a violent and destructive rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud. It is characterized by a twisting funnel-shaped cloud extending from the sky to the ground. Tornadoes are often associated with severe thunderstorms and can cause significant damage to structures and the environment.
Formation
Tornadoes typically form from powerful thunderstorms, known as supercells, which are fueled by warm, moist air rising rapidly into the atmosphere. The combination of wind shear (changes in wind direction and speed with height) and instability in the atmosphere creates a favorable environment for the development of a tornado. When these conditions align, a rotating column of air, called a mesocyclone, may form within the thunderstorm.
The Life Cycle of a Tornado
- Formation Stage: The mesocyclone intensifies and stretches vertically, creating a rotating updraft. As the updraft tightens, a visible condensation funnel descends from the cloud base.
- Mature Stage: The tornado reaches its maximum intensity during this stage. The funnel touches the ground, causing widespread damage as it moves along its path. Strong winds, heavy rain, and large hail are often associated with the tornado.
- Dissipation Stage: The tornado weakens and begins to shrink as the inflow of warm, moist air diminishes. The condensation funnel lifts back into the cloud, and the tornado eventually dissipates.
Characteristics and Dangers
- Tornadoes can vary in size, ranging from a few meters to over a kilometer in width.
- Wind speeds within a tornado can exceed 300 miles per hour (480 kilometers per hour), making them one of the most powerful natural phenomena on Earth.
- The destructive power of a tornado can result in the collapse of buildings, uprooting of trees, and the hurling of debris, causing severe injuries or fatalities.
- Tornadoes can also generate powerful lightning, hail, and intense rainfall, leading to flash floods.
Forecasting and Safety Measures
Meteorologists use advanced weather radar systems, such as Doppler radar, to detect and track severe thunderstorms that may produce tornadoes. When a tornado warning is issued, it is crucial to take immediate action to protect yourself and others. Safety measures include seeking shelter in a basement or an interior room on the lowest floor, away from windows, and covering yourself with a mattress or sturdy furniture for added protection.
Conclusion
Tornadoes are incredibly powerful and destructive natural phenomena that can cause widespread damage and endanger lives. Understanding their formation, life cycle, and associated dangers is essential for forecasting and implementing safety measures to mitigate their impact.
