Lightning protectors were invented by Ben Franklin. It is both a wavelength and particles. This process is extremely fast and impossible to see with the naked eye. The stepped leader generally moves at about 75 miles per second (120 km/s) towards the ground. Lightning can travel both up and down. Fact: Crouching doesn't make you any safer outdoors. The electronic function is almost light speed, but not quite. So does the lightning strike down, or up? It is sometimes best to jump onto the ground when this kind of thing occurs, but often the process is so quick that there is little or no time to react. I have never seen a photo of a partial streak that has only reached partway from the cloud to the ground, and I probably never will, since it happens so quickly. How Should I Prepare for Lightning Storms. Negative charges from a thunderstorm slowly lower to the ground, while positive charges rise from the ground or an object toward the sky. Atoms pass along electrical charge much more quickly than sound vibrations. The stepped leader carries tons of negative charge. I had a friend who was hit by lightning. Because opposites attract, the stepped leader and the negative charge at the ground reach towards each other and quickly meet. Because the cloud is filled with negative charge, it has a lot of current to offer to the newly created discharge path. Each step is less than a millionth of a second long. This process can only be observed with the assistance of extremely quick-exposure cameras. A typical trip duration is 20 milliseconds. In reality, our eyes cannot resolve any of the steps involved. The stepped leader generally moves at about 75 miles per second (120 km/s) towards the ground. These discharges into space are a new subject of study, and are called sprites.

For a negative cloud-to-ground discharge (the most common type of lightning striking the ground), the stepped leader (the channel of ionized air) begins in the lower section of a thunderstorm cloud and propagates downward. This phenomenon occurs because of a difference in charge between a storm cloud and the ground. When you are that close to a storm, you don't stand by the window and watch to see whether the lightning goes up or down. Luckily, we were about to get into the van, so we quickly hopped in. As it nears the ground, it induces enormous quantities of positive charge in the earth, especially at the tips of tall objects. In addition to being an avid blogger, Michael is particularly Methuselah Foundation, the Singularity Institute for Artificial Intelligence, and the Lifeboat Foundation. This describes the common storm cloud, but positively charged storm clouds have been documented. When these two streamers, or ion groups, meet, visible lightning is created. Sound is much slower, being more akin to feeling of the surrounding environment. The path from storm cloud to the surface is complete and the charge can move. And lightning is observed discharging upwards from the charged regions of the cloud in the troposphere. Before them, houses would light on fire when struck by lightning, and the fire department was kept busy during thunderstorms. The interval between steps works out to about fifty-millionths of a second. Lightning Myths and Facts. Does lightning strike from the sky down, or the ground up? AT RIGHT: Photo of ground-to-cloud (upward) lightning striking a television broadcast tower. A lightning bolt is created from the ground up and also down from the sky. Your story scares me a little. Michael is a longtime wiseGEEK contributor who specializes in topics relating to paleontology, This discharge is called the return stroke, and is what we think of when we hear the word "lightning". The return stroke takes around 100 millionths of a second to reach the ground. This is usually the second stage before lightning hits. AT RIGHT: Photo of cloud-to-ground lightning. Let's take a look at the process through which lightning is known to be formed. Advertisement. I was at a beach recently when my family and friends began to notice that our hair was sticking up in a thunderstorm which had suddenly arrived. A typical trip duration is 20 milliseconds. I'm amazed that jumping in the van saved you. Does lightning go up or down? I have been in thunderstorms where the sound of thunder happened so quickly after the flash that I knew I had to be right in the middle of the storm. This is an extremely slow-motion animation- the actual process takes only a small fraction of a second. I have heard stories of people getting struck inside their own homes, and I wanted to get in the spot that was totally windowless and doorless. I suppose the charge from your heads was going up to meet the charge in the sky at that time. Well both actually. Cloud-to-ground lightning comes from the sky down, but the part you see comes from the ground up. Run to a substantial building or hard topped vehicle. The answer is BOTH: There are distinct types of lightning strikes to earth that can travel in either direction - cloud-to-ground lightning and ground-to-cloud lightning. Light is so immensely fast that it goes beyond time. Artificially initiated lightning is associated with things like very tall structures, rockets and towers. This animation depicts the stepped leader descending Luckily, I was inside the house. GO: Home | Storm Expeditions | Photography | Extreme Weather Library | Stock Footage | Blog, Web Site Design and Internet Marketing by CIS Internet, For a negative cloud-to-ground discharge (the most common type of lightning striking the ground), the, Unlike cloud-to-ground lightning which starts inside the thunderstorm, a, Lightning Discharges to TV Towers, Skyscrapers and other Tall Structures.
