Lightning. Forked cloud-to-ground lightning over an urban area at night. 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. Cloud-to-ground lightning occurs between a negatively charged cloud base and the positively charged ground. 'Leader electrons' leave the cloud 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. Rain makes the lightening appear red in colour. Photographed in Pampa,Texas,USA | |
