The temperature of the air in the lightning channel may reach as high as 50,000 degrees Fahrenheit, 5 times hotter than the surface of the sun. Immediately after the flash, the air cools and contracts quickly. This rapid expansion and contraction creates the sound wave that we hear as thunder.
Why does lightning make noise late?
Lightning is seen earlier and thunder is heard later because the speed of sound is 330 m/s and the speed of light is 300,000,000 m/s. Light travels faster than a sound. Thus, light from the lightning reaches first to you. The sound from the lightning takes longer to reach and hence heard later.
Why does thunder sound like a bomb?
The source of the sound you hear as thunder is the rapid expansion of air turned to plasma. The process is a type of explosion. This explosion happens along the entire length of the lightning bolt and take a split second.
How loud is lightning right next to you?
A clap of thunder typically registers at about 120 dB in close proximity to the ground stroke. This is 10 times louder than a garbage truck or pneumatic jackhammer drill. By comparison, sitting in front of speakers at a rock concert can expose you to a continuous 120+ dB level.
Why does lightning not make noise sometimes?
Thunder starts as a shockwave from the explosively expanding lightning channel when a large current causes rapid heating. However, it is possible that you might see lightning and not hear the thunder because it was too far away. Sometimes this is called “heat lightning” because it occurs most often in the summer.
How long does a lightning last?
Lightning is not distributed evenly around Earth, as shown in the map. On Earth, the lightning frequency is approximately 44 (± 5) times per second, or nearly 1.4 billion flashes per year and the average duration is 0.2 seconds made up from a number of much shorter flashes (strokes) of around 60 to 70 microseconds.
How loud is lightning up close?
A clap of thunder typically registers at about 120 dB in close proximity to the ground stroke. This is 10 times louder than a garbage truck or pneumatic jackhammer drill. By comparison, sitting in front of speakers at a rock concert can expose you to a continuous 120+ dB level.
What was the loudest thunder ever recorded?
The explosion was loud enough that this level of noise was recorded many miles away from the site of the blast. A sound of 174 decibels was recorded by barometers 100 miles from Krakatoa. That meant anyone within an 100 mile radius of Krakatoa had a chance of being literally deafened by this sound.
Can thunder shake a house?
Your house will shake depending the closeness of the lightning. Thunder is a sonic boom that comes from the rapid heating of the air around a lightning strike. Sonic booms cause massive shaking to nearby objects (your house). This will happen if the lightning is very close.
Should you shut your windows in a thunderstorm?
If a thunderstorm hits your area the first thing you should do is unplug your computer – or you could risk losing everything on it. Lightning strikes can cause power surges that burn out home computers and monitors leaving them completely worthless.
What lightning smells like?
“It smelled like something inorganic burning, like wires or plastic.” Others have compared the odor to chlorine, cleaning supplies or, unsurprisingly, electrical sparks. Odds are, you’ve smelled lightning-produced ozone before. You know that clean, crisp smell ahead of a springtime rain? That’s it.
How do you know if you’re about to be struck by lightning?
7 Signs That Lightning Is About to Strike You See Tall, Bright White Clouds. You Can Hear the Thunder Approaching. You See Your Hair Standing on End or Feel Tingling. You Taste Something Metallic. You Smell the Scent of Ozone in the Air. You Start to Get Dizzy or Sweat. You Can Hear Vibrating, Buzzing, or Crackling.
How far can a lightning bolt travel?
Lightning can travel 10 to 12 miles from a thunderstorm. This is often farther than the sound of thunder travels. That means that if you can hear thunder you are close enough to a storm to be in danger of being struck by lightning.
Why is there lightning but no rain?
Dry thunderstorm refers to thunder and lightning that occur without bringing rain to the ground. In fact, the thunder-bearing clouds do produce rain but the rain droplets have evaporated in the air before reaching the ground. The anvil cloud is so high that rain coming from it evaporates before reaching the ground.
Is there silent lightning?
Heat lightning, also known as silent lightning, summer lightning, or dry lightning (not to be confused with dry thunderstorms, which are also often called dry lightning), is a misnomer used for the faint flashes of lightning on the horizon or other clouds from distant thunderstorms that do not appear to have.
Can you survive a lightning strike?
Of every 10 people struck, nine will survive. But they could suffer a variety of short- and long-term effects: cardiac arrest, confusion, seizures, dizziness, muscle aches, deafness, headaches, memory deficits, distractibility, personality changes and chronic pain, among others.
What is the longest lightning bolt ever recorded?
In the same study, the WMO found a new candidate for the longest lightning flash by duration, a 17-second continuous burst of lightning from a thunderstorm over Uruguay and northern Argentina in June 2020. That flash pipped the previous record-holder, a 16.73-second flash over Argentina in March 2019.
How does lightning hit the ground?
A cloud-to-ground lightning strike starts as a channel of negative charges called a stepped leader makes its path towards the ground. This entire process occurs so quickly (in less than one second) that lightning appears to travel from the cloud to the ground, when the opposite is true.
What are the 4 types of lightning?
Types of Lightning Cloud-to-Ground (CG) Lightning. Negative Cloud-to-Ground Lightning (-CG) Positive Cloud-to-Ground Lightning (+CG) Cloud-to-Air (CA) Lightning. Ground-to-Cloud (GC) Lightning. Intracloud (IC) Lightning.
