Although Benjamin Franklin demonstrated lightning a

23、s enormous electrical discharge more than 200 years ago, many puzzles still surround this powerful phenomenon.Lightning is generated when electrical charges separate in rain clouds, though processes are still not fully understood. Typically, positive charges build at the cloud top, while the bottom

24、becomes negatively charged. In most instances of cloud-to-ground lightning, the negatively charged lower portion of the cloud repels negatively charged particles on the grounds surfaces, making it become positively charged. The positive charge on the ground gathers at elevated points. A flow of elec

25、trons begins between the cloud and earth. When the voltage charge becomes large enough, it breaks through the insulating barrier of air, and electrons zigzag earthward. We see the discharge as lightning.Lightning can occur within a cloud, between clouds, or between clouds and the ground. The first v

26、ariety, intra-cloud lightning, is the most frequent but is often hidden from our view. Cloud-to-ground lightning, making up about 20 percent of lightning discharges, is what we usually see. Lightning comes in several forms, including sheet, ribbon, and ball. Intra-cloud lightning can illuminate a cl

27、oud so it looks like a white sheet, hence its name. When cloud-to-ground lightning occurs during strong winds, they can shift the lightning channel sideways, so it looks like a ribbon. The average lightning strike is more than 3 miles long and can travel at a tenth of the speed of light. Ball lightn

28、ing, the rarest and most mysterious form, derives its name from the small luminous ball that appears near the impact point, moves horizontally, and lasts for several seconds.Thunder is generated by the tremendous heat released in a lightning discharge. Temperatures near the discharge can reach as hi

29、gh as 50,000 F within thousandths of a second. This sudden heating acts as an explosion, generating shock waves we hear as thunder.About 2,000 thunderstorms are occurring in the world at any tie, generating about 100 lighting strikes every second, or 8 million daily. Within the United States, lightn

30、ing strikes are estimated at 20 million a year, or about 22,000 per day. You have a l-in-600,000 chance of being struck by lightning during your lifetime. Lightning can strike twice or more in the same spot. The Empire State Building in New York is struck by lightning about two dozen times annually.
