Lightning. Multiple in-cloud lightning bolts. Lightning occurs when a large electrical charge builds up in a cloud. This is probably due to the rapid movement of water droplets and ice particles in the turbulent interior of the cloud. In-cloud lightning occurs between the negatively charged base of a cloud and the positively charged upper levels. 'Leader electrons' move between the charged areas and when contact is made,there is a huge backflow of energy along the path of the electrons. This produces a bright flash of light and temperatures of up to 30,000 degrees Celsius. Lightning appears red when there is rain in the cloud. Photographed in Gillette,Wyoming,USA | |
