What is the sound of a thunderstorm?
The sudden increase in temperature and hence pressure caused by the lightning produces rapid expansion of the air in the path of a lightning bolt. In turn, this expansion of air creates a sonic shock wave, often referred to as a “thunderclap” or “peal of thunder”.
What is louder thunder or lightning?
Our ears perceive thunder based upon the distance from lightning. The sound is loudest closest to the ground. Thunder varies as sound waves travel away from the bolt, resulting in a longer-lasting rumbling. Lightning cooks air so fast that the blast expands air to 48,632°F, resulting in an explosion in every direction.
What is heavy thunderstorm?
A severe thunderstorm is a thunderstorm that contains large hail, 1 inch in diameter or larger, and/or damaging straight-line winds of 58 mph or greater (50 nautical mph). Rain cooled air descending from a severe thunderstorms can move at speeds in excess of 100 mph. This is what is called “straight-line” wind gusts.
What was the worst thunderstorm in history?
DES MOINES, Iowa — The derecho storm in Iowa from this summer is the most expensive thunderstorm disaster in U.S. history. The National Oceanic and Atmospheric Administration is estimating total damage valued at $7.5 billion.
How do kids make storm sounds?
How to Create a Thunderstorm:
- Snap your fingers (the sound of light rain falling)
- Clap your hands together.
- Slap your hands on your legs (at this time a student can flick a light switch on and off to represent lightning).
- Stomp your feet.
What produces sound of Thunder?
Thunder is the sound produced by the rapid heating of air by a lightning strike. Essentially, thunder is the sound produced by lightning. When lightning strikes, the narrow channel of air through which it travels reaches temperatures of up to 30,000 °C almost instantly.
What is the sound of Thunder mainly about?
Thunder, sound caused by a lightning discharge. Lightning heats the air in its path and causes a large over-pressure of the air within its channel. The channel expands supersonically into the surrounding air as a shock wave and creates an acoustic signal that is heard as thunder.
What causes the sound of Thunder in the sky?
Thunder is caused by lightning. When a lightning bolt travels from the cloud to the ground it actually opens up a little hole in the air, called a channel. Once then light is gone the air collapses back in and creates a sound wave that we hear as thunder.
What sound does a Thunder make?
Thunder may consist of claps, peals and crackle. A deep booming sound, similar to a sonic boom, is called a peal; a typical rumble is a clap and the high-pitched crackling sound sometimes heard before the main peals or claps are crackles.
