Watch this video to learn about what causes lightning! Click here to download this video (1920x1080, 102 MB, video/mp4). So, do thunderclouds have rubber shoes? Not exactly, but there is a lot of shuffling going on inside the cloud. Lightning begins as static charges in a rain cloud. Winds inside the cloud are very turbulent. Water droplets in the ...
The electric field "looks" for a doorknob. Sort of. It looks for the closest and easiest path to release its charge. Often lightning occurs between clouds or inside a cloud. But the lightning we usually care about most is the lightning that goes from clouds to ground—because that's us! As the storm moves over the ground, the strong negative charge ...
In a fraction of a second, lightning heats the air around it to incredible temperatures—as hot as 54,000 °F (30,000 °C). That's five times hotter than the surface of the Sun! The heated air expands explosively, creating a shockwave as the surrounding air is rapidly compressed. The air then contracts rapidly as it cools. This creates an initial CRAC...
Each year, about 400 people in the U.S. are struck by lightning while working or playing outside. About 50 people are killed and several hundred more are left to cope with permanent disabilities. The summer months of June through September are the deadliest as far as lightning is concerned. In 2022, 19 people died across the US from lightning strik...
Here are some important rules to remember about lightning safety: 1. First rule of lightning safety: No place outside is safe near a thunderstorm. 2. Plan your outdoor activities so that you can get to a safe place in case a thunderstorm develops. 3. Remember: When thunder roars, go indoors! If you can hear thunder, the storm is near enough to you ...
Lightning observed by the GOES-16 Geostationary Lightning Mapper (GLM) illuminates the storms developing over southeast Texas on the morning of February 14, 2017. Lightning is an important part of weather forecasting. The Geostationary Lightning Mapper instrument on the GOES-R series satellites can detect lightning activity over nearly the whole We...

Thunder is effectively exploding air, and when heard close to the lightning channel, it consists of one large bang. At about 1 km away, it is heard as a rumble with several loud claps. Distant thunder has a characteristic low-pitched rumbling sound. However, beyond 16 km, thunder is seldom heard.
Thunder is created when lightning passes through the air. The lightning discharge heats the air rapidly and causes it to expand. The temperature of the air in the lightning channel may reach as high as 50,000 degrees Fahrenheit, 5 times hotter than the surface of the sun.
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.
16. Mai 2023 · The short answer is that an unequal distribution of electrical charges cause a static discharge, which we call lightning, while thunder is the sound that results from the rapid expansion and contraction of air around a lightning strike. Lightning causes thunder.
