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. (When a cloudâs name ends in nimbus, it means rain or snow is falling from the cloud.) The cloud increases in size and begins to build up peaks, which become very dark.
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.
