The heat wave that we are experiencing this week has also given way to a stormy night with a great festival of lightning in the sky, as can be seen in these images in Las Fotos de los Lectores de La Vanguardia captured in Manlleu, in the region from Osona.
Lightning is a powerful natural electrical discharge of static electricity, produced during a thunderstorm, which generates an electromagnetic pulse.
The precipitated electric discharge of lightning is accompanied by the emission of light (lightning), caused by the passage of electric current, which ionizes the air molecules, and by the sound of thunder, developed by the shock wave.
Electricity (electrical current), passing through the atmosphere, rapidly heats and expands the air, producing the characteristic noise of thunder.
Summer storms can give rise to these powerful natural electrical discharges of static electricity and offer us a real spectacle of light and sound in the sky, like fireworks.
