- Definição2
- Sudden electrical discharges manifested by a flash of light (lightning) and a sharp or rumbling sound (thunder). Thunderstorms are associated with convective clouds (Cumulonimbus) and are, more often, accompanied by precipitation in the form of rainshowers or hail, or occasionally snow, snow pellets, or ice pellets.

- Definição3
- In general, a local storm, invariably produced by a cumulonimbus cloud and always accompanied by lightning and thunder, usually with strong gusts of wind, heavy rain, and sometimes with hail. It is usually of short duration, seldom over two hours for any one storm. A thunderstorm is a consequence of atmospheric instability and constitutes, loosely, an overturning of air layers in order to achieve a more stable density stratification. A strong convective updraft is a distinguishing feature of this storm in its early phases. A strong downdraft in a column of precipitation marks its dissipating stages. Thunderstorms often build to altitudes of 40 000–50 000 ft in midlatitudes and to even greater heights in the Tropics; only the great stability of the lower stratosphere limits their upward growth. A unique quality of thunderstorms is their striking electrical activity. The study of thunderstorm electricity includes not only lightning phenomena per se but all of the complexities of thunderstorm charge separation and all charge distribution within the realm of thunderstorm influence.

- Contexto
- The trend forecast shall indicate the expected onset or cessation of one or more of the following weather phenomena or combinations thereof: — freezing fog — low drifting dust, sand or snow — blowing dust, sand or snow — thunderstorm (without precipitation) — squall — funnel cloud (tornado or waterspout).
- Current techniques for determining the various characteristics of thunderstorms would make it possible to define a useful descriptive and concise measure (“index”) of thunderstorm activity, but no such general index exists yet.
