What Causes Thunder?

Thunder is a sound wave created by lightning. Lightning causes a rapid increase in temperature, which results in a quick expansion of the surrounding air. This expansion creates a shock wave, perceived as the sound of thunder.

• Lightning heats the air to temperatures hotter than the sun’s surface.
• The air rapidly expands and contracts, causing sound waves.

The Science Behind the Sound

The varying intensity of thunder is due to the distance from the listener to the lightning. The closer the lightning, the louder and quicker the thunder sound.

• Thunder travels at the speed of sound, approximately 343 meters per second.
• If you see lightning and hear thunder simultaneously, the storm is directly overhead.
• Delay in the sound indicates the distance of the lightning strike.

Influencing Factors

Several factors can influence the sound and intensity of thunder:

• Geography: Mountains and buildings can amplify or muffle the sound.
• Intensity of the lightning stroke: More intense lightning produces louder thunder.
• Weather conditions: Humidity and air temperature affect sound waves.

The Role of Thunder in Weather Prediction

Thunder plays a significant role in understanding impending weather conditions. Meteorologists use thunder, along with other storm indicators, to predict the severity of storms and necessary safety measures.

• Thunderstorms often indicate the possibility of severe weather such as hail or tornadoes.
• The frequency and interval of thunder can help in tracking storm movement.

Thunderstorm Safety Tips

Safety during thunderstorms is crucial to avoid harm from both lightning and secondary effects.

• Seek shelter indoors or in a vehicle.
• Avoid electrical appliances and plumbing fixtures.
• Stay away from windows and doors.
• Do not use trees for shelter as they attract lightning.

Frequently Asked Questions

1. Can thunder harm you directly?
No, thunder itself cannot harm you. It is the lightning that accompanies it which poses a risk.

2. Why does thunder rumble for a long time?
Rumbling occurs because the sound from different parts of the lightning channel reaches you at different times.

3. Is it safe to talk on a cell phone during a thunderstorm?
Yes, as long as your phone is not plugged into a charger.

4. How far away can you hear thunder?
Under ideal conditions, thunder can be heard up to 25 miles away.

5. What should you do if caught outside during a thunderstorm?
Seek shelter in a car or building. Avoid open fields, hilltops, and water bodies.
