Spherical lightning refers to spherical lightning (physical phenomenon): spherical lightning, commonly known as rolling thunder. It usually happens in thunderstorms, and it is spherical lightning. This is a real physical phenomenon. It is very bright, almost spherical, and its diameter is about 15 to 40 cm. It usually lasts only a few seconds, but it also lasts 1 to 2 minutes. In addition to the common orange and red, there are yellow, purple, blue, bright white and dark green auras, showing a variety of colors.

Extended data:

For a long time, there is no exact explanation for the formation of spherical lightning. 20 12 June, a scientist from China, Lanzhou City, Gansu Province, photographed a luminous ball during a thunderstorm in Qinghai Province, which was considered as spherical lightning in thunderstorm weather. Its video and spectrum are considered to be the first scientific record of spherical lightning in nature so far. The details of this research have been published in the June 20 14 issue of Physical Review Letters.
