pioruny

Piorun is the Polish word for a lightning bolt, and pioruny refers to multiple bolts. It denotes the natural electrostatic discharge that occurs in the atmosphere during thunderstorms and is closely associated with thunder.

Lightning forms when electric charges separate within a storm cloud or between the cloud and the ground, driving a rapid current that heats air to extremely high temperatures and creates a thunderous sound. Typical voltages reach hundreds of millions of volts, currents can reach several thousand amperes, and individual flashes last from tens to hundreds of microseconds to a few milliseconds.

Common categories of lightning include cloud-to-ground (CG) discharges, intra-cloud (IC) discharges, and cloud-to-cloud (CC) discharges. Modern observations also document upper-atmosphere phenomena such as sprites, blue jets, and halos that occur above storm systems.

Lightning is a worldwide phenomenon, with higher frequency in tropical and subtropical regions and during active thunderstorm seasons in temperate areas. It poses hazards to people, buildings, and aircraft; safety measures emphasize avoiding exposure during storms, seeking shelter indoors, staying away from tall objects and open water, and unplugging sensitive equipment when feasible.

In Slavic folklore, Perun is the god of thunder, and the Polish lexicon associates the term piorun with thunder and with the god’s weapon in literary and cultural contexts. Today, the word is used in meteorology and science communication and can appear in idiomatic expressions or as a symbol of sudden power or danger.
