Thunderstorms and Lightning

Also referred to as a lightning storm, a thunderstorm is a weather form wherein thunder and lightning are present. Thunderstorms, most especially if accompanied by heavy rains and downburst winds, pose hazards to people and the environment.

How many thunderstorms occur each day?

The U.S. averages about 1200 tornadoes per year which works out to an average of about 3.3 per day.

It is far from an even distribution, though. First, tornadoes are far more common in spring and summer than in the winter and activity varies from year to year. Second, tornadoes often occur in outbreaks with major events sometimes producing several dozen tornadoes in a single day. Between outbreaks there can be periods of little to no tornado activity. The largest number of tornadoes observed in 24 hours is 208 set on April 27, 2011.

Accurate global statistics are not available as many countries do not keep records of tornadoes.

What is often associated with very severe thunderstorms called supercells?

Supercells are often associated with very severe weather conditions such as tornadoes, large hail, strong winds, and heavy rain. These storms have a rotating updraft, known as a mesocyclone, which can support the development of intense and long-lasting severe weather.

What happens before lightning strikes?

Before lightning strikes, electrical charges build up within a storm cloud. As the charges separate, a negative charge forms at the bottom of the cloud and a positive charge builds up on the ground below. When the difference in charge becomes strong enough, a conductive path is created for the lightning bolt to travel between the cloud and the ground.

How far can lightning strike?

When you see a lightning bolt, start counting how many seconds till you hear thunder. Divide that number by 5 and that tells you how far away the lightning bolt was in miles. http://www.easycalculation.com/weather/lightning.php

What happens if lightning hits lava?

When lightning strikes lava, it can split the lava flow into fragments called volcanic bombs. The intense heat of the lava can also cause the moisture in the air to rapidly expand, leading to thunder and potentially creating fine volcanic ash. Additionally, the interaction between lightning and lava can generate magnetic fields that provide scientists with valuable information about the eruption.

What is the sound following a flash of lightning?

This is called thunder, and results from a rapidly expanding pressure wave, as a narrow column of air is heated to thousands of degrees by the lightning's electrical energy.

What is the pitch of a sound is most closely related to?

The pitch of a sound is most closely related to the frequency of the sound wave. Higher frequency sound waves are perceived as higher pitch, while lower frequency sound waves are perceived as lower pitch.

If lightning strikes your car what happens?

Basically... nothing! You will hear of course a verry big noise, you will see a intense violet light. Possibly you will feel smell of ozone. The lightning will discharge itself through the car's metall body in the ground, and due to the Faraday effect it will not break into the car. It's possible that one or more tires will burst. Keep the windows closed!!! All this is not valable anymore if you are travelling in a soft top car. You will be possibly dead after a lightning strike! ---------------------------------- It can very well blow out the electronics in the car regardless of the rubber tites. I have seen several cases of this happening.

Can you see thunder?

yea u cna see it if its loud enough to shake your windows otherwise no u just hear thunder u see lighting

What was the Biggest hailstone ever recorded in the UK?

A hailstone fell on Horsham, Sussex on September 5th 1958, weighing 190g. It's the heaviest hailstone ever recorded in Britain.

Can you get killed by thunder?

yes u can esepcially if ur not under somethinge its veary likely that u can die

When did browning start making citori white lightning?

Browning began producing the Citori White Lightning model in 2015. It is a versatile over/under shotgun known for its lightweight design and classic aesthetics.

Is smoke hotter than fire?

A fire burn consumes your skin as fuel and would keep going until the fuel is gone or it is deprived of oxygen. A steam burn is just water or a liquid that has a lot of thermal energy that it wants to transfer to something that is colder (like your skin). A fire burn would persist, while a steam burn would just get it's thermal energy sapped out and condense into a liquid.

If you hear thunder 12 seconds after you see the flash of lightning. how far away is the thunderstorm?

Sound takes about 4.6 seconds to travel one mile.

So 12 seconds divided by 4.6 = 2.6 miles away.

However, since you're probably asking on behalf of Novel Stars, that needs to be converted to kilometers.

2.6 miles = 4.18429 kilometers. So 4 km.

I don't know what "Novel Stars" is, but people who have grown up with a background wouldn't do the calculation starting of with miles. They probably know that the sound travels 333 meters per second, therefore it takes three seconds to cover one kilometer. Therefore 12 seconds = 4 kilometers.

(The result is the same as above but the path to get there is different.

What is atmospheric discharge?

An atmospheric pressure discharge is an electrical discharge in air at atmospheric pressure.

An electrical discharge is a plasma, which is an ionized gas. Plasmas are sustained if there is a continuous source of energy to maintain the required degree of ionization and overcome the recombination events that lead to extinction of the discharge. Recombination events are proportional to collisions between molecules and thus to the pressure of the gas. Atmospheric discharges are thus difficult to maintain as they require a large amount of energy.

Typical atmospheric discharges are:

  • DC arc
  • Lightning
  • Atmospheric Pressure Glow Discharge (APGD)
  • Dielectric Barrier Discharge (DBD)

Is fork lightning more dangerous than sheet lightning?

Sheet lightning, or more accurately intracloud lightning is the same as lightning that hits the ground, the only difference is that it is within the cloud. They are no different apart from that. They are the exact same thing, except one would take a different path. They are both dangerous.

Who has got struck by lightning and survived?

Matt Thompson in Keystone Colorado was struck directly through his body.

There are stories of people all over the world that have got hit by a lightning and survived.

A key factor is that they have been working out and been covered in sweat or being very wet from rain itself.

This seem to have saved them from the actual current going through the body instead of outside of body.

Some people wearing necklaces have even had these melted/burned into the skin around their neck due to the intense power of the lightning.

I have even heard about one single person being hit by lightning 3 times. I think the lightning got the better of him the last time, but he survived the first two.

It is an interesting fact that people can survive such an experience.

It is however so many people throughout the world with such an experience that it is a bit difficult to actually make a list of them all here.

I cant really see the use of it. I am sure most of them prefer a nice and calm life.

Traveling faster than the speed limit increases both the risk and the?

Traveling faster than the speed limit increases both the risk of accidents and the severity of potential injuries. It also decreases the driver's reaction time, making it more difficult to avoid hazards on the road. It is important to always follow posted speed limits to ensure your safety and the safety of others.

What does hypernatremia occur at?

Hypernatremia occurs when there is an excess of sodium in the blood, leading to a higher-than-normal sodium concentration. This can happen due to dehydration, excessive sodium intake, or certain medical conditions affecting fluid balance in the body.

How can you tell if a storm is moving toward or away from you?

I'm assuming that this question implies how you can tell this without using advanced equipment. Some people believe that you can count the time between lightening and its associated thunder. If the time difference between the two follows an increasing trend then the storm is moving away from you. However if you just compare two different lightening strikes you cannot judge movement of the storm because lightening can strike up to 10 miles away from the center of the storm. Hope that helps.

Does a violin make a high pitched sound or a low pitched sound?

A violin typically produces high-pitched sounds. The pitch of the sound is determined by the frequency of the vibrations of the strings, and violins are designed to produce frequencies corresponding to high pitches.

Is electricity faster than sound?

Yes. In air, sound travels at about 300 or 330 meters/second (it varies, depending on the temperature - also, sound in water or steel, for example, is quite a bit faster). But an electrical signal can go at about 2/3 the speed of light in a vacuum - that would be about 200,000 kilometers/second.
