Why does lightning happen and what is the way to prevent it ?
Lightning is a natural electrical discharge that occurs during thunderstorms. It is caused by the buildup and discharge of electrical energy in the atmosphere. The exact mechanism of lightning formation is still not completely understood, but it is generally believed to involve the separation of electric charges within a thunderstorm cloud.
Thunderstorms are characterized by the presence of strong updrafts and downdrafts of air. These movements cause ice particles and water droplets to collide and interact, leading to the separation of positive and negative charges within the cloud. The positive charges accumulate at the top of the cloud, while the negative charges concentrate at the bottom. As the charge separation intensifies, it creates a large electric field between the cloud and the ground.
When the electric field becomes strong enough, it ionizes the surrounding air molecules, creating a conductive path for the electrical discharge. This discharge, or lightning bolt, occurs as a rapid movement of electrons from the negatively charged region to the positively charged region. The bolt of lightning can travel within the cloud (intra-cloud lightning), from the cloud to the ground (cloud-to-ground lightning), or between different clouds.
Preventing lightning is not possible, as it is a natural atmospheric phenomenon. However, there are measures that can be taken to mitigate the risks associated with lightning strikes:
Seek shelter: If you are outdoors during a thunderstorm, find a substantial building or a fully enclosed metal-topped vehicle to take shelter in. Avoid seeking shelter under trees or near tall objects.
Stay indoors: If you are already indoors, it is generally safe. However, it is recommended to stay away from windows, doors, electrical appliances, and plumbing fixtures during a thunderstorm.
Avoid open areas: If you are caught in an open area during a thunderstorm, it is important to move to a lower area. Lightning tends to strike the tallest objects, so it is safer to be in a low-lying area.
Stay away from water: Avoid swimming, boating, or being in bodies of water during a thunderstorm, as water is an excellent conductor of electricity.
Lightning protection systems: For buildings and structures, lightning protection systems can be installed. These systems consist of lightning rods and conductive materials that help to direct lightning safely into the ground, reducing the risk of damage.
It's important to note that while these measures can help reduce the risks associated with lightning, they do not completely eliminate the possibility of lightning strikes. It is always advisable to stay informed about weather conditions and follow safety guidelines provided by local authorities during thunderstorms.
