What causes thunder? Thunder is caused by the rapid expansion and contraction of the air surrounding a lighting bolt. On average, a lightning bolt is about 5 times hotter than the surface of the sun or about 50,000°F!

Thunder Cumulonimbus clouds often form thunderstorms. Thunder is the sound caused by lightning. Depending on the distance and nature of the lightning, thunder can range from a sharp, loud crack to a long, low rumble (brontide). The sudden increase in pressure and temperature from lightning produces rapid expansion of the air surrounding and within a bolt of lightning.

What weather conditions are most likely to cause thunderstorm and tornado ? Rating Newest Oldest. Best Answer: The most basic conditions to produce thunderstorms and tornadoes are cold dry air and warm moist air. The warm air rises through the cold air and forms clouds. The stronger the differences between air masses; the more likely that a thunderstorm will form. However, when the air masses are very different, super cell thunderstorms occur and can produce tornadoes. http://en.wikipedia.org/wiki/Thunderstor... http://www.nssl.noaa.gov/edu/safety/torn...

What  causes the sound of thunder? Thunder Fun Facts: 1  To judge how close lightning is, count the seconds between the flash and the thunderclap. Each second represents about 300m (984.25ft). 2  Thunder is not only heard during thunderstorms. It is uncommon, but not rare, to hear thunder when it is snowing. 3  Lightning does not always create thunder.

What  causes the sound of thunder? Vertical lightning is often heard in one long rumble. However, if a lightning bolt is forked, the sounds change. The shock waves from the different forks of lightning bounce off each other, the low hanging clouds, and nearby hills to create a series of lower, continuous grumbles of thunder. Thunder Fun Facts:

What causes a thunderstorm? Thunderstorms result from the rapid upward movement of warm, moist air, sometimes along a front. As the warm, moist air moves upward, it cools, condenses, and forms a cumulonimbus cloud that can reach heights of over 20 kilometres (12 mi). As the rising air reaches its dew point temperature, water vapor condenses into water droplets or ice, reducing pressure locally within the thunderstorm cell.

Preparing Your Trip Thunder travels at about one mile for every five seconds or, one kilometre for every three seconds. If the wind changes in a clockwise direction, fair weather is on the way. If the wind changes in a counterclockwise direction, fair weather is leaving. Doubling of wind speed quadruples its strength.

Thunderstorm However, lightning and the noise of thunder creates the thunderstorms and if there are certain types of clouds in the sky – cumulonimbus, then it could result in thunderstorms. On most occasions, thunderstorms will bring on heavy rain falls and strong winds.

lightning A flash of light in the sky caused by an electrical discharge between clouds or between a cloud and the Earth's surface. The flash heats the air and usually causes thunder. Lightning may appear as a jagged streak, a bright sheet, or, in rare cases, a glowing red ball.

Severe Weather 101 Thunder is caused by lightning. The bright light of the lightning flash caused by the return stroke mentioned above represents a great deal of energy. This energy heats the air in the channel to above 50,000 degrees F in only a few millionths of a second!

If you can hear thunder are you close enough to get struck by lightng in a thunder storm? The sound that lightning causes is the the thunder. You can see the flash of lightning before you hear the sound because light travels much faster t … han sound. Sometimes the lightning is obscured by the clouds so you do not see the flash but you hear the sound, so you might think you heard the sound first. Answered.

- The loud sound that thunder makes is due to the heat of the flash of lightning. This heat causes the air to suddenly expand (grow bigger) and then contract (grow smaller). The noise we hear is the sound of this violent expansion and contraction. The sound of thunder may go on rolling for several seconds.

Thunder and lightning Thunder and lightning are some of the most dramatic weather phenomena in the UK. They are caused through the formation of cumulonimbus clouds and usually last no more than half an hour.

How Do Thunderstorms Happen? 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.

Thunder: Superstitions and Folklore And likewise, when you hear thunder in the winter, it is a precursor to very cold weather. The first thunder in spring is a sign that the winter is broken.

Severe Weather 101 No, it is not possible to have thunder without lightning. Thunder is a direct result of lightning. 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.

What  causes the sound of thunder? What causes the sound of thunder? From the clouds to a nearby tree or roof, a lightning bolt takes only a few thousandths of a second to split through the air. The loud thunder that follows the lightning bolt is commonly said to come from the bolt itself. However, the grumbles and growls we hear in thunderstorms actually come from the rapid expansion of the air surrounding the lightning bolt. As lightning connects to the ground from the clouds, a second stroke of lightning will return from the ground to the clouds, following the same channel as the first strike.

(t). Thunderstorms and Tornadoes Thunderstorms Thunderstorms form when moist, unstable air is lifted vertically into the atmosphere. Lifting of this air results in condensation and the release of latent heat. The process to initiate vertical lifting can be caused by: (1). Unequal warming of the surface of the Earth.

A Scientific Explanation of What Causes Thunder In order to understand thunder causes, one needs to know about lightning first. Well! Lightning is the electricity discharged during a thunderstorm. Lightning is caused due to build-up and discharge of electrical energy in the thunderstorm clouds, which average about 15,000 to 25,000 feet above sea level. Lightning usually occurs within clouds, between the cloud and air or between the ground and cloud.

How do you get thunder and lightning without rain? Lightning does not come from rain; it comes from static electricity charges in the Earth and atmosphere. Lightning, the 'flash', is the electric discarge itself; thunder, the 'bang', is the sound of air rushing back after being superheated by thelightning bolt.

What Causes Thunder? Thunder is caused by the sudden expansion of the air around a lightning bolt's path. The deep rumbling and sharp cracks of thunder are produced as the air around the lightning bolt is superheated — up to about 54,000° Fahrenheit (about 33,000° Celsius) — and rapidly expands.
