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.
