Lightning is one of the most common and least understood phenomena in meteorology.
Larger View
Lightning is one of the most common and least understood phenomena in meteorology. It is also one of the most dangerous. Each year, lightning kills eighty to one hundred people in the United States. When lightning strikes electrical lines, the resulting power interruptions and blackouts can be hazardous as well as annoying. This episode of NOVA follows several teams of investigators collecting information and images to answer questions such as how lightning is formed, how to predict and prevent lightning strikes, and how to protect people from its dangers. Closed captioned for the hearing impaired.
