The phenomenon is a “double sealed sphere”, where the strong electrostatic pressure is constrained by the electron pressure non-isothermal plasma.
Ball lightning is formed by the compression of the gas in which the photons move, reports the Chronicle.info with reference to lenta.ua.
According to physicists, light compresses air by means of an optical electrostriction pressure. Electrostrictive called the changing shape of the dielectrics.
The compressed air due to the optical properties prevent the free flow of photons which are in a kind of trap. As a result of ordinary white light begins to rotate inside the trap in all directions, which increases its intensity.
The publication Science Alert notes that proposed by researchers in the physical model still cannot explain some types of ball lightning observed in nature.
In 2014, it was reported that Chinese physicists received spectrum of the “fireball”, and also filmed her appearance and evolution. Spectrum analysis of plasma showed the presence of emission lines characteristic of silicon, iron, and calcium items in large quantities present in the soil.
Physicists believe ball lightning “plasma formation”, “plasmoid” – it has electric charge, the potential difference of which between the soles of the feet and a human head is about 200 volts. In stormy weather, the strength is increased about 100 times. The magnitude of the charge of ball lightning is a few microcolonies. It is able to kill a man.

A ball of lightning about 5% of the cases, see falling from storm clouds, in 0.5% see rising in the clouds, and in 75% of cases it is floating in the atmosphere.
