- Mani Gandham, adtech/enterprise/software/startups. Views. Thunder is the sound caused by lightning. When a lightning bolt strikes, the air immediately around it is superheated by the pressure and temperature of the electricity. This heated air rapidly expands and creates a sonic shock wave similar to a bomb explosion or when a jet breaks the sound barrier.

What causes thunder? The light from the flash reaches us in a fraction of a second, whereas the sound lags along like a snail following an interplanetary rocket. The audiovisual spectacle of thunder and lightning is a combination of the dynamics of the vibration of air molecules and their disturbance by electrical forces.

Noise Atmospheric noise or static is caused by lighting discharges in thunderstorms and other natural electrical disturbances occurring in the atmosphere. These electrical impulses are random in nature. Hence the energy is spread over the complete frequency spectrum used for radio communication.

- Read on to find a range of facts, trivia and other interesting information about thunder. Thunder is the sound caused by lightning. The intense heat from lightning causes the surrounding air to rapidly expand and create a sonic wave that you hear as thunder.

Thunder and lightning Thunder and lightning. Thunder and lightning are some of the most dramatic weather phenomena in the UK. They are caused through the formation of cumulonimbus clouds and usually last no more than half an hour. A thunderstorm is a series of sudden electrical discharges resulting from atmospheric conditions. These discharges result in sudden flashes of light and trembling sound waves, commonly known as thunder and lightning. Thunderstorms are associated with convective clouds and are often accompanied by precipitation.

- The connection is made and the protons rush up to meet the electrons. It is at that point that we see lightning and hear thunder. A bolt of lightning heats the air along its path causing it to expand rapidly. Thunder is the sound caused by rapidly expanding air. © 2012 UCAR.

- Lightning is caused by the build up of electrostatic charge in clouds. One region within the cloud builds up a positive charge and the other a negative charge.The process is not completely understood as to why, but the bottom of the cloud usually ends up being negatively charged and the top positively charged.f the build up (separation) of charge becomes great enough, the negative charges may leap to the positive side of another cloud, this is called sheet lightning or it may leap to the ground. The animation shows he creation of a ground strike of lightning.

Thunder: Lightning's Sound Waves Thunder is the name given to the loud sound waves created by lightning. The lightning channel heats and expands quickly and explosively, causing a violent disturbance in the air surrounding the strike that radiates outward for a short distance as a supersonic (faster than sound) shock wave. The shock wave eventually slows to a normal sound wave a short distance later:

How thunder sounds Light travels at 300,000 km/second, whereas sound travels at 0.3 km/sec. This is why you can see the flash of lightning sooner than you hear the rumble of thunder that the initial lightning strike produces. As the distance to the lightning strike increases, the pitch of the thunder lowers.

Lightning Distance Calculator The delay between when you see lightning and when you hear thunder occurs because sound travels much, much slower than light. Sound travels through air at about 1100 to 1200 feet per second (our default is 1150). That is a little more than one mile per five seconds. This approximation will give you a good idea of how far away the lightning was.

What causes thunder? Richard Brill, a professor at Honolulu Community College, explains: Thunder is caused by lightning, which is essentially a stream of electrons flowing between or within clouds, or between a cloud and the ground. The air surrounding the electron stream is heated to as hot as 50,000 degrees Farhenheit, which is three times hotter than the surface of the sun.

- If you hear the sound of thunder, then you are in danger from lightning. Lightning kills and injures more people each year than hurricanes or tornadoes; between 75 to 100 people. IF YOU’RE INDOORS: Avoid water. It’s a great conductor of electricity, so do not take a shower, wash your hands, wash dishes or do laundry.

- When the rain starts pelting the roof and lightning fills the sky, the animals are relieved. The sky must be trying to protect them by scaring Storm away! But when everything stops and the sky is quiet, the animals hear the thump, thump of someone coming toward the barn.

Understanding Lightning: Thunder Thunder is the sound caused by a nearby flash of lightning and can be heard for a distance of only about 10 miles from the lightning strike. The sound of thunder should serve as a warning to anyone outside that they are within striking distance of the storm and need to get to a safe place immediately!

How thunder sounds The sound of thunder will also sound different depending on whether the channel of lightning is associated with cloud to cloud lightning overhead (parallel) or cloud to ground lightning to the side of you (perpendicular). A sound commonly associated with thunder is the clap. This type of sound occurs when the lightning channel is perpendicular to the observer’s line of sight.

A Scientific Explanation of What Causes Thunder A lot of theories has been discussed concerning causes and creation of thunder. In the third century BC, it was believed that thunder is caused due to collision of clouds. However, the most accepted theory was conceived in the 20th century. According to this theory, lightning causes thunder sound.

- Lightning is a bright flash of electricity produced by a thunderstorm. All thunderstorms produce lightning and are very dangerous. If you hear the sound of thunder, then you are in danger from lightning. Lightning kills and injures more people each year than hurricanes or tornadoes; between 75 to 100 people. What causes lightning?

- Lightning is caused by an electrical charge in the atmosphere that is unbalanced. The movement of rain and ice inside a thundercloud creates an electrical charge, with the negative charge (electrons) forming at the bottom of the cloud and the positive charge (protons) forming at the top. Opposites attract so the negative charge at the bottom of the cloud seeks out a positive charge to connect with.

- No there is not, Heat Lightning is really just lightning in a distant storm. The reason you can't hear it is because the sound of thunder can travel approximately 25 miles. When light can travel a lot farther.

A Scientific Explanation of What Causes Thunder Thunder is the sound generated due to lightning. The flash of lightning and the accompanying thunder occur around the same time. Nonetheless, we all are aware that lightning is seen first, followed by the sound of thunder after few seconds. This phenomenon occurs as light wave travels much faster than the sound waves.
