C2G, or "Cloud to Ground," refers to a type of lightning that occurs when electrical discharge travels from a cloud to the Earth's surface. This phenomenon is part of the broader study of atmospheric electricity and is crucial for understanding weather patterns and storm behavior. C2G lightning can pose significant risks, including damage to structures and injury to living beings. It is often associated with severe weather events, such as thunderstorms, and is a key focus for meteorologists and safety organizations like the National Weather Service. Understanding C2G helps improve safety measures during storms.
