The Nature of Ball Lightning by Stanley Singer

By Stanley Singer

In 1837 a entire dialogue of lightning seemed within the Annual of the French Bureau des Longitudes with a piece on ball lightning which supplied for the 1st time a available resource within the clinical literature of the elemental homes of this curious traditional phenomenon. the writer, Francois Arago, was once the dominant effect within the French Academy of Sciences within the 19th century, having join that august physique on the age of twenty-three. His consciousness by myself no doubt served at the moment to set up the validity of clinical curiosity within the challenge. additionally his dialogue lined a few of the significant questions linked to ball lightning in a nota­ bly clear-sighted, powerful variety. Later reconsideration of an analogous questions frequently supplied no major development over Arago's dialogue. There a dauntless band of various yet consistently small quantity who tried to account for an it appears easy typical prevalence, a ball of fireside often visible in thunderstorms, with the simplest wisdom that advancing technological know-how may supply. All makes an attempt to house this phenomenon have been in­ variably annoyed. The features of ball lightning may be effortlessly cataloged, yet they firmly resisted either experimental replica and theo­ retical clarification. One might say that to this present day there's no rationalization permitted through numerous scientists. numerous investigators of serious skill and significant accomplishment in several fields of technology, together with Faraday, Kelvin, and Arrhenius, took notice of the problem.

Explosions, temperatures high enough to melt metals, strong electric effects, and force sufficient to deflect the craft from its path. The generation of the fireballs in completely closed spaces is further shown to include structures almost entirely surrounded by metal. 9. Ball lightning has been reported in connection with volcanic eruptions and cyclones. An electrical storm with many strong discharges and strong field effects occurred on the lee side of a volcano in Guatamala in 1902. Corona discharges were seen on people and houses everywhere, and there were many lightning balls which burst with muffled explosions but caused no damage.

The entire mass was somewhat oval in shape, a few centimeters longer than it was wide. The ball moved steadily at first along a line of floats in the river which protruded 10 to 15 cm above the water. This path took it somewhat at an angle to the prevailing wind toward the observer on the bank (see Fig.

Ball lightning was seen at a distance of 30 min 1951 by a scientist of an atmospheric-electricity research institute in Germany.
