Lightning is a discharge of electricity. A single stroke of lightning can heat the air around it to 30,000°C (54,000°F)! This extreme heating causes the air to expand explosively fast. The expansion creates a shock wave that turns into a booming sound wave, known as thunder.
What causes lightning and thunder?
Thunder is caused by the rapid expansion of the air surrounding the path of a 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.
How does lightning happen?
Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds. This heat causes surrounding air to rapidly expand and vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash.
Can there be thunder without lightning?
No, it is not possible to have thunder without lightning. 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. Thunder is caused by lightning.
Who made lightning?
“The lightning rod was invented by Benjamin Franklin, but perfected decisively by Nikola Tesla.”Apr 30, 2019.
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.
What are the 3 types of lightning?
There are three common types of lightning: cloud to ground, cloud to cloud and cloud to air. Cloud to ground lightning is the most dangerous. The ground is mainly consisted of positively charged particles while the bottom of violent storm clouds have negative charged particles.
Where does lightning strike the most?
The most lightning-struck location in the world Lake Maracaibo in Venezuela is the place on Earth that receives the most lightning strikes. Massive thunderstorms occur on 140-160 nights per year with an average of 28 lightning strikes per minute lasting up to 10 hours at a time.
What does it mean when lightning keeps flashing?
Understanding Lightning: Continuing Current/Hot Lightning Flashes which contain both return strokes and continuing current are also common. These flashes will flicker, leaders/return strokes, and also have short periods of constant illumination, continuing current.
What does it mean when thunder is really loud?
If the thunder sounds more like a rumble, the lightning was at least several miles away. The loud boom that you sometimes hear is created by the main lightning channel as it reaches the ground. Remember, if you can hear thunder, chances are that you’re within striking distance of the storm.
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.
What color is lightning?
The distinctive blue-white color of lightning is caused by light emitted as the electrons drop back to their original energy states. Seen from above, lightning storms also produce less well-known emissions of blue or red light above the clouds, known as jets and sprites.
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.
Can men create lightning?
It is entirely possible to create static electricity, and even lightning using this method. Van de Graaf generators, for example, use rubbing to generate voltages in excess of a 1,000,000V. Artificial lightning (in miniature) is regularly created in places like NEETRAC at Georgia Tech. An artificial lightning bolt.
What color lightning is the strongest?
White – this is by far one of the most dangerous color of lightning due to the fact that this type of lightning is the hottest. This color can indicate a low concentration of moisture in the air as well as a high concentration of dust in the air.
What is the weakest color of lightning?
The color of the bolt depends on how hot it is; the hotter the lightning, the closer the color will be to the end of the spectrum. The color spectrum in this case start with infared which is red and the coolest up to ultraviolet which appears violet and is the hottest.
What weather causes lightning?
In the summer, thunderstorms typically develop in the afternoon when the sun heats air near the ground. If the atmosphere is unstable, bubbles of warm air will rise and produce clouds, precipitation, and eventually lightning.
Can humans create thunderstorms?
HUMANS CAN ACCIDENTALLY CAUSE THEM. Studies have shown that increased temperatures in and around cities, due to the urban heat island effect, can trigger thunderstorms that wouldn’t have otherwise formed in these areas if the city and its streets weren’t there.
What is dark lightning?
Dark lightning is a burst of gamma rays produced during thunderstorms by extremely fast moving electrons colliding with air molecules. Researchers refer to such a burst as a terrestrial gamma ray flash.
Why do trees get hit by lightning?
WHY LIGHTNING STRIKES TREES They’re especially prone to lightning strikes because electricity seeks the path of least resistance, and the sap and moisture inside a tree make it a better conductor than the surrounding air.
