Term for complex meteorological phenomena associated with airborne electrical discharges (lightning and thunder). On average, around 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)).

Wetter - Blitzschlag, Regen

Especially in connection with the dreaded hail, thunderstorms can cause great damage to vineyards. The discharge of lightning occurs almost exclusively via the wire frames of the 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, storms and wind can also cause considerable damage to young shoots in particular. See also climate, meteorology, precipitation and weather.

There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
