How can distance to a lightning bolt be determined?

How can distance to a lightning bolt be determined?

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. Five seconds, for example, indicates the lightning struck 1 mile away, and a 10-second gap means the lightning was 2 miles away.

Is counting the seconds between lightning and thunder accurate?

Yes, it is a very accurate way of determining the distance of a thunderstorm. From either seeing the flash of lightning or hearing the burst of static interference on an AM radio and hearing the thunder then counting the time in seconds and dividing that number be 5 gives you the distance in miles.

How far away is lightning per second?

The Correct Method to Calculate Lightning Distance

If thunder is heard The lightning is . . .
15 seconds after a flash 3 miles away
20 seconds after a flash 4 miles away
25 seconds after a flash 5 miles away
30 seconds after a flash 6 miles away

How long does it take sound to travel 1 mile?

roughly 5 seconds
As you can see, the speed of sound changes depending on the temperature and the humidity; but if you want a round number, then something like 350 meters per second and 1,200 feet per second are reasonable numbers to use. So sound travels 1 kilometer in roughly 3 seconds and 1 mile in roughly 5 seconds.

How far away is thunder when you hear it?

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!

What is the maximum speed of sound?

about 36 kilometres per second
But the maximum speed of sound moving through a solid or a liquid has just been calculated for the first time. It is about 36 kilometres per second, more than 8000 times lower than the speed of light in a vacuum.

What are 5 warning signs that a tornado may occur?

Warning Signs that a Tornado May Develop

  • A dark, often greenish, sky.
  • Wall clouds or an approaching cloud of debris.
  • Large hail often in the absence of rain.
  • Before a tornado strikes, the wind may die down and the air may become very still.
  • A loud roar similar to a freight train may be heard.

    What does it mean when thunder is really loud and long?

    The louder-than-normal thunder are common in Elevated Thunderstorms. These storms start to rise from the warm, muggy air above the ground. However, because of the temperature inversion air warming as you go up, in Elevated storms, the sound waves are trapped near the ground or get bent back toward earth or refracted.
