It is quite probable that there are

It is quite probable that there are several different physical forms of ball
lightning, each having its own characteristic set of properties. These phenomena are
rare and this rarity leads to the wide variety of descriptions of ball lightning.
Lightning balls seem to appear near the end of severe electrical storms. This
happens after the air has been highly ionized and is filled with electromagnetic
disturbances generated by the conventional lightning.
The diameters of observed lightning balls range from a few inches to rare
instances of many feet. The average diameter of a ball is about 10 inches. The balls
usually move by rolling or sliding along conductors such as telephone wires, fences,
and other metallic objects.

One large ball was observed to hang near the base of a cloud for 15 minutes. The calculated surface temperature of a lightning ball can be as high as 5,000°C. When the ball decays, a great amount of energy is released.

The Soviet physicist Pyotr Kapitsa was the first to present a reasonable explanation for the majority of the questions in a hypothesis for ball lightning. His

ideas on the energy balance, on the importance of resonance phenomena, and on the fixed dimensions of "ball lightning are, well known. The theory put forward by him

in 1955 starts with the description of a powerful flash of lightning at the end of a thunderstorm. It paves the way for the appearance of ball lightning at sufficient ionization of the air and the presence of vapours necessary for ionization of the rising current of air. The ionized clouds of plasma are composed of the atomic nuclei of gas

stripped of their electrons. These nuclei possess their own 'periods of electromagnetic oscillations and are able to absorb the incoming external electromagnetic energy of the same period. This is known as the resonance effect.

Details of Kapitsa's hypothesis include the reasoning that during the luminescence period, some energy is supplied continuously into the ball lightning and

the energy source is outside the ball. This reasoning is based on the conservation of energy principle and on the realization that the ball lightning is suspended in the air

with no visible link with the energy source* Thus the only source of energy is the absorption of intense outside radio waves. The resonance characteristic of the absorption process is determined by the form of the ball lightning alone and by its

dimensions. For effective absorption of radio waves by the lightning ball, the natural frequence of the electromagnetic oscillations within the ball, must coincide with the natural period of the absorbed radiation.

As to academician Kapitsa, his field of interests was not limited by high temperatures alone. In 1978 he was given a Noble prize for his fundamental discoveries and inventions in the field of low temperatures and superconductivity.

Вполне вероятно, что есть несколько различных физических форм мячмолнии, каждый из которых имеет свой собственный характерный набор свойств. Эти явления являютсяредкие и это редкость приводит к широкому разнообразию описаний шаровая молния. Молнии шарики, как представляется, появляются ближе к концу сильной грозы. Этопроисходит после того, как воздух сильно ионизированный и заполнены с электромагнитнымпомехи, порожденных обычными молнии. Диаметры наблюдаемых молнии шаров варьируются от нескольких сантиметров до редкихэкземпляры многих футов. Средний диаметр шара составляет около 10 дюймов. Шарыобычно передвигаются качения или скольжения вдоль проводов, таких как телефонные провода, заборы,и другие металлические предметы. Один большой шар был замечен повиснуть у основания облака на 15 минут. Расчетные температуры поверхности молнии шара может быть выше, чем 5 000 градусов Когда мяч распадов, освобождается большое количество энергии.Советский физик Пётр Капица был первым представить разумное объяснение для большинства вопросов в гипотезу для шаровой молнии.
