Can you hear thunder from 30 miles away?
Thunder is the sound produced by lightning and generally cannot be heard more than about 15 miles from the nearest point of the lightning bolt, though the upper limit of audibility can, at times, approach 30 miles.
What is the 30 30 rule for lightning?
Don’t forget the 30-30 rule. After you see lightning, start counting to 30. If you hear thunder before you reach 30, go indoors. Suspend activities for at least 30 minutes after the last clap of thunder.
How far is lightning when you hear thunder?
A general rule of thumb to know how far off a bolt of lightning is when you hear thunder, if you count the number of seconds between the flash of lightning and the sound of thunder, and then divide by 5, you’ll get the distance in miles to the lightning: 5 seconds = 1 mile, 15 seconds = 3 miles, 0 seconds = very close.
How far can you see lightning?
‘ All lightning comes from a thunderstorm, but you can see that lightning many miles away from a storm when the sky is clear (clear away from the storm, of course). How far? Depending on visibility conditions, you can see lightning from as far as 150 to 200 miles away on a dark summer night.
Can you see lightning from 100 miles away?
At night, it is possible to see the flashes of lightning from very far distances, up to 100 miles (160 kilometres), but the sound does not carry that far.
Why is thunder so loud?
A big noise Why is thunder so loud? It’s because the amount of electrical energy that flows from the cloud to the ground is so enormous: it’s like a very big waterfall of electricity. The louder the sound that you hear, the closer you are to the lightning. Light travels through air much faster than sound.
Is it OK to have your AC on during thunderstorm?
Though it’s tempting to rely on your air conditioner, you shouldn’t run your unit during a thunderstorm. Not only does running your AC during a storm put your system at risk, but it can also put your safety at risk.
Should I unplug electronics during a thunderstorm?
Keep Your Computer Plugged In Anything that’s plugged into an outlet in your home is at risk of suffering damage from an electrical surge during thunderstorms. If an electrical storm has been forecast, unplug your computer, laptop, and other devices, and consider unplugging appliances.
Does counting seconds between lightning thunder work?
Typically, a sharp crack or click will indicate that the lightning channel passed nearby. If you count the number of seconds between the flash of lightning and the sound of thunder, and then divide by 5, you’ll get the distance in miles to the lightning: 5 seconds = 1 mile, 15 seconds = 3 miles, 0 seconds = very close.
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.
How can you tell how far away lightning is without thunder?
Just count the number of seconds that pass between a flash of lightning and the crack of thunder that follows it, then divide that number by five. The resulting number will tell you how many miles away you are from where lightning just struck.
Can lightning silent?
The phenomenon that is called silent or heat lightning is simply cloud-to-ground lightning that occurs very far away, with thunder that dissipates before it reaches the observer and cannot be heard. Met Office meteorologist Nicola Maxey explained: “It’s not an unusual phenomenon.
Is it safe to take a shower while its lightning?
No. Lightning can travel through plumbing. It is best to avoid all water during a lightning storm. Do not shower, bathe, wash dishes, or wash your hands.
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 lightning hotter than the sun?
In fact, lightning can heat the air it passes through to 50,000 degrees Fahrenheit (5 times hotter than the surface of the sun). When lightning strikes a tree, the heat vaporizes any water in its path possibly causing the tree to explode or a strip of bark to be blown off.
What is red lightning?
Sprites, also known as red lightning, are electrical discharges that appear as bursts of red light above clouds during thunderstorms. The researchers hope to learn more about the physical and chemical processes that give rise to sprites and other forms of upper atmospheric lightning.
Can you swim in heat lightning?
A: Swimming during a thunderstorm is one of the most dangerous things you can do. Lightning regularly strikes water, and since water conducts electricity, a nearby lightning strike could kill or injure you. To be really safe, you should not swim in an indoor pool when lightning is around.
