What is the definition of lightning?

The definition of lightning is accurately described as a luminous manifestation associated with a sudden electrical discharge. Lightning occurs when there is an imbalance of electrical charges in the atmosphere, typically during a thunderstorm. This discharge can result in a bright flash of light, which is the visible manifestation of the electrical energy being released as a result of the rapid movement of electrons between clouds or between a cloud and the ground.

Understanding lightning is essential for weather observation and safety measures, especially in severe weather conditions. This phenomenon can produce significant atmospheric effects, including thunder, which is the sound produced by the rapid expansion of air heated by the lightning discharge.

The other options relate to aspects of meteorology but do not accurately define lightning. Warm rising air and wind patterns concern atmospheric dynamics, while frozen precipitation involves solid forms of water, such as ice or snow, which are distinct from electrical discharges.
