11 wrz 2024 · 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.
NASA’s lightning data, collected from the ground, air, and space, help scientists understand lightning patterns and predict severe weather. Lightning is the electrical discharge between positively and negatively charged regions within clouds. Visually, lightning is comprised of bright flashes of light called strokes.
Lightning is a large-scale natural spark discharge that occurs within the atmosphere or between the atmosphere and the Earth’s surface. On discharge, a highly electrically conductive plasma channel is created within the air, and when current flows within this channel, it rapidly heats the air up to about 25,000°C.
Lightning occurs commonly during thunderstorms as well as other types of energetic weather systems, but volcanic lightning can also occur during volcanic eruptions. Lightning is an atmospheric electrical phenomenon and contributes to the global atmospheric electrical circuit.
8 paź 2024 · Lightning strikes on people, though comparatively rare, can cause conditions ranging from amnesia to cardiac arrest. Lightning can also cause the surrounding air to heat up to 27,700 degrees Celsius (almost 50,000 degrees Fahrenheit), often setting nearby objects on fire.
16 maj 2023 · Thunder is the sound of the pressure wave produced when lightning instantaneously heats air and then it suddenly cools. Thunder and lightning accompany thunderstorms, volcanoes, and heat waves, but have you ever wondered what causes thunder and lightning. The short answer is that an unequal distribution of electrical charges cause a static ...
1 paź 2005 · Despite lightning's familiarity, however, no one knows why lightning leaders behave this way. Lightning within clouds is far more common than lightning that strikes the ground.
