Lightning can be defined as a transient, high current electric discharge whose path length is generally measured in kilometers. Lightning occurs when some region of the atmosphere attains an electric charge sufficiently large that the electric fields associated with the charge cause electrical breakdown of the air. However lighting has been reported in snowstorms, sandstorms, in clouds over erupting volcanoes, and been reported to occur in the clear air. Such lightning can take place entirely within a cloud (intra cloud), between two clouds, between cloud and the earth, or between a cloud and the surrounding air. There really aren't differrent 'types' of lightning, almost all lightning discharges occur in basically the same way. However, varying conditions and situations that lightning occurs in make the flash look different, with a few exceptions, and names have been given to describe them. Here is a list of the most common 'types' of lightning: 'Anvil Crawlers'- lightning that branches upward and outward like a tree along the tops and sides of large thunderstorms. The lightning seems to 'travel' or 'crawl' across the sky. Anvil Lightning- (also called a 'bolt from the blue')- Dangerous type of lightning that extends away from the storm cloud and strikes the ground away from the storm. Ball Lightning- An unexplained, rare, floating ball of light that occurs during thunderstorms. Bead Lightning-A rare occurence where separate illuminated sections remain for a short duration along ...

Lightning if formed when cold air and warm air meet, the warm air, being lighter, blows over the cold air. This makes thunderstorm clouds! The cold air has ice crystals. The warm air has water droplets. During the storm, the droplets and crystals bump togeth...

Lightning is a bright flash of electricity produced by a thunderstorm. There are cold air and warm air. When they meet, the warm air goes up. It makes thunderstorm clouds! The cold air has ice crystals. The warm air has water droplets. During the storm, the droplets and crystals bump together and move apart in the air. This rubbing makes static electrical charges in the clouds. Just like a battery, these clouds have a "plus" end and a "minus" end. The plus, or positive, charges in the cloud are at the top. The minus, o...

There is no absolute protection against lightning because of its random and capricious nature. However, the risk of being struck by lightning can be substantially reduced. There are general safety rules that apply to all athletic and recreational events. The athlete should have a proactive plan that can be instituted when storms approach. He/she should go to a safe shelter before the storm arrives and stay there until the danger is gone. Because the location, climate, terrain and playing site vary w...

Water and ice move around inside the cloud; forced up by warm air currents, down by gravity and compressed in the cloud. Just as rubbing balloon can create static electricity, particles in the cloud become charged. It’s not clear how it happens but charges separate in the c...
