How Lightning Forms
All rights reserved. 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. Other visible bolts may appear as bead, ribbon, or rocket lightning. During a storm, colliding particles of rain, ice, or snow inside storm clouds increase the imbalance between storm clouds and the ground, and often negatively charge the lower reaches of storm clouds.
How does the lightning "know" where to discharge—or strike?
How does lightning form?
Clouds may look fluffy and innocent, but they are actually active places. At their most exciting, they can create the wondrous effect of lightning. 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 a balloon can create static electricity, the particles in the cloud become charged. Positive charges move up, and negatives move down. Once a significant charge separation has built up, the positive and negative charges seek to reach each other an neutralise.
Lightning is a naturally occurring electrostatic discharge during which two electrically charged regions in the atmosphere or ground temporarily equalize themselves, causing the instantaneous release of as much as one billion joules of energy. Lightning causes thunder , a sound from the shock wave which develops as gases in the vicinity of the discharge experience a sudden increase in pressure. Lightning occurs commonly during thunderstorms and other types of energetic weather systems. The three main kinds of lightning are distinguished by where they occur: either inside a single thundercloud , between two different clouds, or between a cloud and the ground. Many other observational variants are recognized, including " heat lightning ", which can be seen from a great distance but not heard; dry lightning , which can cause forest fires ; and ball lightning , which is rarely observed scientifically. Humans have deified lightning for millennia, and lightning-inspired expressions like "Bolt from the blue", "Lightning never strikes twice in the same place " and " blitzkrieg " are in common usage. In some languages, the notion of "Love at first sight" literally translates as "lightning strike".
