What are thunderstorms caused by?
A thunderstorm caused when warm and moist air rises and swift updraft to colder regions of the atmosphere affecting the zone with its irresistible destruction, is an intense, short-lived weather disturbance. It is a storm associated with the presence of lightning, thunder, formation of dense clouds, heavy rain, and strong gusty winds. Thunderstorms sometimes turn to dangerous storms possessing lightning, powerful winds, hail, and may lead to floods and tornadoes. Now let us move forward to understand what are the causes and effects of thunderstorms.

What causes a thunderstorm?
When warm moist air meets cold dry air, the warm air rises; the water vapor condenses in the air, and forms a cloud. As the water vapor condenses, it releases heat, which is a form of energy. A large amount of the thunderstorm's energy comes from the condensation process that forms the thunderstorm clouds. As the thunderstorm progresses, eventually the rain cools the entire process down and the energy is gone.
Why do thunderstorms occur in nature?
Thunderstorms help keep the Earth in electrical balance. The Earth's surface and the atmosphere conduct electricity easily as the Earth is charged negatively and the atmosphere, positively.
What is lightning?
Lightning is a form of electricity in the atmosphere. During the first millionth of a second in a common lightning strike, a negative charge probes downward from the cloud. At the same time, a positive charge probes skyward. When they connect, up to one billion watts of electricity blasts upwards. The air in the lightning bolt turns into plasma, as hot as 50,000°F, ten times hotter than the surface of the sun.
What damage can lightning do?
Lightning strikes can set trees or houses on fire. Lightning can enter your home by following wires and pipes that go into the ground; it can also travel through metal reinforcing wire or bars in concrete and explode. Lightning often knocks out power lines and sends powerful electrical surges through electrical and phone lines. Once in your home, they can burn out appliances and other electronics.
What is thunder?
Thunder is caused by lightning. When a lightning bolt travels from the cloud to the ground it actually opens up a hole in the air, called a channel. Once then light is gone the air collapses back in and creates a sound wave that we hear as thunder. The reason we see lightning before we hear thunder is that light travels faster than sound.
What happens when lightning strikes a building?
Heavy rains can lead to flood. Flood waters can plow through earthen dams, pull homes off their foundations and sweep them away, knock out power lines, and contaminate drinking water for weeks.
