A thunderstorm is a type of weather event known for its occurrence of lightning and thunder. These storms are triggered by the swift upward movement of warm, moist air. As the air rises, it cools down and condenses, resulting in the formation of clouds. Within these clouds, water droplets collide and interact, generating static electricity. Eventually, this accumulated electricity is discharged, leading to the occurrence of lightning. The heat produced by lightning rapidly expands the surrounding air, creating the distinct sound we perceive as thunder.
