When a lightning bolt travels from the cloud to the ground it actually opens up a little 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 basic ingredients used to make a thunderstorm are moisture, unstable air and lift. You need moisture to form clouds and rain. You need unstable air that is relatively warm and can rise rapidly. Finally, you need lift. Thunder is caused by lightning. When a lightning bolt travels from the cloud to the ground it actually opens up a little 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. Lightning is a bright flash of electricity produced by a thunderstorm. All thunderstorms produce lightning and are very dangerous. If you hear the sound of thunder, then you are in danger from lightning. Lightning kills and injures more people each year than hurricanes or tornadoes; between 75 to 100 people. Even small thunderstorms are dangerous. Every thunderstorm produces lightning, which kills more people than tornadoes each year. Thunderstorms also cause heavy rain, flash flooding, hail, strong winds and tornadoes. When warm and cold air masses meet, a thunderstorm can grow. In this activity, you will learn about convection and how air moves. (WWLP) – Tuesday was another severe weather day for parts of the Midwest, but strong thunderstorms and even tornadoes occasionally occur here in western Massachusetts as well. Intense storms dropped large hail that coated the ground in parts of Kansas, Nebraska, and Missouri Tuesday. Damaging winds were also a concern.

A thunderstorm, also known as an electrical storm, a lightning storm, or a thundershower, is a type of storm characterized by the presence of lightning and its acoustic effect on the Earth's atmosphere known as thunder. Thunderstorms occur in association with a type of cloud known as a cumulonimbus. A thunderstorm is a storm where you hear thunder and see lightning. Usually there is heavy rain in a thunderstorm. Thunderstorms are electric storms. When there is about to be a thunderstorm, a cumulonimbus cloud forms, often in a clear blue sky.
