Lightning and cumulonimbus clouds, time-exposure image. Lightning occurs when a large electrical charge builds up in a cloud during a storm. When the electric charge is released, it produces a bright flash of light and temperatures of up to 30, 000 degrees Celsius. Cumulonimbus clouds form when atmospheric instabilities allow strong updrafts of warm, moist air to keep rising and condensing, up to altitudes of around ten kilometres. The end result is typically a storm with thunder and lightning. | |
