What Causes Lightning?

Lightning is created by the clash of two clouds
In thunderclouds bottom is usually negative and top is positive.

Which are the Worst Places to be on a Storm

Under a Tree - Lightning typically strikes to the tallest object, because it requires the shortest distance between cloud and the tree, and the tree is a conductor of electricity (it has water inside)
On a sailboat - Cruise ships and well-equipped yachts are very dangerous to be on a lightning storm on water, only when it has lightning protection system installed, the electricity will mostly be driverted to the water.

How Lightning is Formed

The particles in the cloud become charged. It’s not clear how it happens, but charges separate in the cloud. 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 and neutralise.

As the negative charge races down, the air surrounding it heats up.The spark almost 20,000 degrees Celsius, and it rapidly heats the air to create a shock wave.

How Understand the Distance of a Lightning

To find out how far away the storm is, you can count how long you hear the sound after the lightning. For every 4 seconds between the flash and the rumble, the thunderstorm is 1 mile away that is close to 1,4 km

What is a Lightning Conductor?

Lightning conductor is a metal rod or metallic object mounted on top of an elevated structure, such as a building, a ship, or even a tree, electrically bonded using a wire or electrical conductor to interface with ground

How does a Lightning Conductor Works?

As a lightning protection system, lightning conductors have the job to protect buildings and tall structures. And it works like this: if a lightning strike the structure it will hit the lightning conductor and be conduct the lighting strike to the ground though wires

Interesting Facts:

Lightning bolts can travel at speeds of up to 60,000 miles per second. Every second around 100 bolts of lightning strike the Earth.


One lightning bolt has enough electricity to power 200,000 homes. You're more likely to be struck by lightning than by eaten by a shark.
