Term for complex meteorological phenomena associated with airborne electrical discharges (lightning and thunder). On average, about 1600 thunderstorms occur on 0.3% of the earth's surface. In earlier times, it was believed that thunderstorms had a negative effect on wine quality (the subject is described in the work "Weinbuch: Von Baw, Pfleg und Brauch des Weins" by the clergyman Johann Rasch (1540-1612)). Especially in connection with hail, thunderstorms can cause great damage to the vineyard. The discharge of lightning occurs almost exclusively via the wires of the vine training systems and can affect entire rows of vines. The green shoots and leaves turn grey-green and dry out. Vines affected by lightning can die completely within a few days. Rain, storm and wind can also cause considerable damage, especially to young shoots. See also under climate, precipitation and weather.
